GATE ECE 1988 | Sampling Question 31 | Signals and Systems

A signal containing only two frequency components (3 kHz and 6 kHz) is sampled at the rate of 8 kHz, and then passed through a low pass filter with a cutoff frequency of 8 kHz. The filter output

is an undistorted version of the original signal.

contains only the 3 kHz component.

contains the 3 kHz component and a spurious component of 2 kHz.

contains both the components of the original signal and two spurious components of 2 kHz and 5 kHz.
