How do you test a low-pass filter?

When testing a low-pass filter, generally you have to use an arbitrary waveform generator (Arb) to create test tones to pass through the filter to measure the relative gain or attenuation of each tone to find the cutoff frequency of the filter.

What is the output of low-pass filter?

The cutoff frequency for a low-pass filter is that frequency at which the output (load) voltage equals 70.7% of the input (source) voltage. Above the cutoff frequency, the output voltage is lower than 70.7% of the input, and vice versa.

What is the conclusion of low-pass filter?

CONCLUSION From this experiment, we are proving the theory of the characteristics of filters. Low-pass filter allows frequencies lower than the cut-off frequency while high-pass filter allows frequencies higher than the cut-off frequencies. Band-pass filter allows frequencies in the bandwidth.
