Question 3:
a.) A signal with frequency of 9 kHz and amplitude of 200 µV is input to a low pass filter with cutoff frequency of 700 kHz. What are the frequency and amplitude of the output signal?
b.) A signal with frequency of 7 Hz and amplitude of 6 V is input to a low pass filter with cutoff frequency of 1 kHz. What are the frequency and amplitude of the output signal?
Homework Answers
Answer:-a) The input signal frequency (9 kHz) is less than the cut-off frequency (700 kHz) of the LPF. Hence signal is simply passed through the filter. Hence output signal is same as input signal.
Answer:-b) In this case also, the input signal frequency is less than cut-off of LPF. Hence same signal is passed to output of the LPF.
