EC > GATE 2017 SET-2 > Sampling Theorem
The signal x(t)=sin(14000πt) where t is in seconds, is sampled at a rate of 9000 samples per second. The sampled signal is the input to an ideal lowpass filter with frequency response H(f) as follows:
What is the number of sinusoids in the output and their frequencies in kHz?
Correct : b
