Why low pass filter is used in AM demodulation?
The main element of AM demodulation is to create the base-band signal. This can be achieved by using a simple diode and rectify the signal. The filtering by R-C low pass filter removes the all unwanted high frequency elements from the input signal.
Which filter is used in demodulation?
Digital Demod Filter Overview
Data filtering is used in digital demodulation to limit bandwidth and reduce intersymbol interference.
How does low pass filter affect amplitude?
A low pass filter is a circuit whose amplitude (magnitude) function decreases as increases, that is, the circuit passes low frequencies (relatively large amplitudes at the output) and rejects high frequencies (relatively small amplitudes at the output) as shown in fig. 1.
What is low pass filter in signal processing?
A low-pass filter (LPF) is a circuit that only passes signals below its cutoff frequency while attenuating all signals above it. It is the complement of a high-pass filter, which only passes signals above its cutoff frequency and attenuates all signals below it.
