Question 40
|
A low pass filter is:
|
Passes the frequencies lower than the specified cutoff frequency
|
|
|
Used to recover signal from sampled signal
|
|
|
Rejects higher frequencies
|
|
|
All of the above
|
Question 40 Explanation:
A low-pass filter (LPF) is a filter that passes signals with a frequency lower than a selected cutoff frequency and attenuates signals with frequencies higher than the cutoff frequency. The exact frequency response of the filter depends on the filter design.
