The main disparity between LPF-low pass filter and high pass filter-HPF is the frequency range which they exceed. An HPF (high pass filter)is one kind of circuit which permits the high frequency and blocks low frequency for flowing through it. In the same way, an LPF (low pass filter)is one kind of circuit which permits the low-frequency and blocks high-frequency for flowing through it. In filters, the cut off frequency will decide the range of high frequency as well as low frequency. Before discussing the filter operational method, we have to know the required components of these filters. The LPF and HPF can be designed with electronic components like resistor, amplifier, capacitor, etc.

What is Low Pass Filter and High Pass Filter?
An overview of low pass filter and high pass filter with differences are discussed below.
L Voice Filter
Low Pass Filter
The circuit diagram of the low pass filter is shown below. The circuit of LPF can be built with a resistor as well as a capacitor in series so that the output can be achieved. Once the input is given to the circuit of the LPF, then the resistance will give a stable obstacle, however, the capacitor position will have an effect on the output signal.
If the high-frequency signal is applied to the LP circuit, thus it will exceed from resistance which will offer the standard resistance, however, the resistance accessible from the capacitor will be nothing. This is due to the resistance offered from the capacitor toward the high-frequency signal will be zero whereas the low-frequency signal is unlimited.
From the above circuit of the low pass filter, It is understandable that once the high-frequency signal comes LPF circuit afterward the capacitor will permit it to flow as well as it will pass to the GND. In this state, the o/p voltage achieved will be zero because the whole voltage is supplied to ground.
However when the low-frequency signal goes through the LPF circuit then the output will be generated, as the resistance will give a similar obstacle like the high-frequency signal although the capacitor will offer infinite resistance.
Therefore, in this state, the signal cannot flow through the lane of the capacitor. So the total low-frequency signal will be supplied to the output terminal.
High Pass Filter
The circuit diagram of the high pass filter is shown below. An HPF blocks the low-frequency signals & allows just high-frequency signals for flowing through it. Even though it provides reduction to high-frequency signal also however the attenuation issue is so little that it can be ignored. This can be obtainable by the resistor and capacitor characteristics.
When the input signal is applied to the capacitor, then the voltage across the resistor can be achieved because of the o/p voltage. The combination of the resistance of the resistor as well as a capacitor can be called reactance.
Xc = 1/2пfc
From the above equation, we can conclude that the reactance will be inversely proportional to the cut-off frequency. When the input signal's frequency is superior, then the reactance will be low. Similarly, when the input signal's frequency is low, then the reactance will be low.
Difference between Low Pass Filter and High Pass Filter
The difference between low pass filter and high pass filter mainly includes definition, circuit architecture, significance, operating frequency, and applications.
| Low Pass Filter | High Pass Filter |
| LPF circuit allows the frequency underneath cut-off frequency for flowing through it. | HPF circuit allows the frequencies over cut-off frequency for flowing through it. |
| It can be built with a resistor which is followed by a capacitor. | It can be built with a capacitor which is followed by a resistor. |
| It is important in eliminating the aliasing effect. | It is important whenever the distortion occurs because of low-frequency signal like noise is to be detached. |
| It is lesser than the cut-off frequency. | It is higher than the cut-off frequency. |
| The LPF can be used as an anti-aliasing filter in communication circuits. | The HPF can be used in amplifiers like low noise, audio, etc. |
Thus, this is all about the main differences between the low pass filter and high pass filter, circuit working, and low pass and high pass filter graphs. From the above information, finally, we can conclude that the HPF circuit allows the high-frequency signals which are high than the cut-off frequency whereas the LPF circuit allows the low-frequency signals which are low then the cut-off frequency. In the above low pass and high pass filter experiment, the two filters we have discussed in the above are passive filters because the circuits of these filters utilize passive components. The signal gain can be enhanced with the help of amplifiers in the circuit so that it will become an active filter. Here is a question for you, what are the applications of LPF and HPF?
Hey there and welcome to our Chipmunk Voice Changer, which will let you experience what your voice would sound like as a high-pitched, squeaky chipmunk voice. Don't forget to play with the drop-down menu provided so you can experiment with different 'intensities' of the chipmunk voice effect.
You don't need to download any software to use this, and it's completely free. Just click the 'record a clip' button to create a voice recording that we'll add microphone effects to. If you're feeling playful, there's an option to upload a voice recording of someone else.
Even though chipmunks don't really have a 'voice', we all know what a chipmunk voice is, and can all imagine what it sounds like - a high-pitched, squeaky, sped-up version of a human voice. It tends to make even adult voices sound like a child's voice, and can range from a tolerably cute voice to annoying. It can sometimes appear in popular culture (in tv shows and movies) for comedic effect when something is being sped up.
People generally find the chipmunk voice cute and funny, and it became a phenomenon so popular that a musical group and subsequent movie were made about it. Alvin and the Chipmunks was originally created as a novelty music group, with each chipmunk given a distinct personality and child-like voice.
L Voice Filter Reviews
Largely due to the novelty of the voice effects in the movie (which was a musical, so plenty of opportunity for adorable singing), it was well-received as a children's movie and the makers went on to create three more films, each with the transformed voices that people (mostly kids) loved so much.
L Voice Filter Vs
It's commonly known that if you'd like to modify your voice, you can do so by inhaling a bit of helium (see our Helium Voice Changer for this!) - but with our voice converter, you don't need helium balloons or the tech used to make movies or musical groups.
If you enjoyed using this voice modulator, you may also like the microphone effects found at voicechanger. Over there you'll find free audio changers that will transform the pitch and frequency of your voice, and will let you emulate the vocals of some popular fiction characters.
Feedback and suggestions are always welcome here, so if there's a new voice filter you'd like to see, or improvements you think should be made, let us know in the comments or in the suggestions box.
