When a low pass filter is used with a sine wave input, the output is also a sine wave. The output will be reduced in amplitude and phase shifted when the frequency is high, but it is still a sine wave. This is not the case for square or triangular wave inputs. For non-sinusoidal inputs the circuit is called an integrator.
Gaussian low pass filter is a image smoothing filter which is used to smooth up a digital image...........
The lowest frequency of an LC low-pass filter is zero, i.e. DC.
A: This is term used to describe a filter that has wide or a big range of frequency available to pass trough. There are others name to describe other ranges of frequency like low pass, hi pass, narrow pass.
Type your answer here..yes.
A: Installing a low pass filter is only required if the frequency are not there or to eliminate the low frequency, If it is an audio amplifier you never will need low frequency since your mine hears cannot hear those frequency.
That is its function. An RC low pass circuit is an integrator.

A low pass filter allows "low" frequencies to pass through a circuit and blocks higher frequencies.
Earth is low pass filter, because it tends to absorbe the amblitude of the high frequency waves.
low pass or high pass
In a DC power supply, a low-pass RC filter is typically used to "filter the voltage" by reducing or eliminating any remaining ripple. This works because such ripple has frequency components over 0 Hz (ripple is essentially an AC component with an offset), which are suppressed by the low-pass filter.
by combining a low-pass filter with a high-pass filter.[1]
A low pass removes frequencies ABOVE a set level. A high pass removes frequencies BELOW a set level. A separate high pass filter can be used to route only frequencies over, say, 80 Hz to your main speakers (if your receiver/processor did not have this function). Then you would set the low pass filter on the subwoofer to 80 Hz to reject signal above that level.

Butterworth filter
A: This is term used to describe a filter that has wide or a big range of frequency available to pass trough. There are others name to describe other ranges of frequency like low pass, hi pass, narrow pass.
Answer: In some demodulaters like synchronous detector carrier is multiplied. then obtained wave form is passed through low pass filter. here carrier is removed In some demodultors such as square law detector non linear device is used and there after low pass filter is used. At low pass filter carrier is filtered
