GATE ECE 1998 | Sampling Question 24 | Signals and Systems

A 1.0 kHz signal is flat - top sampled at the rate of 1800 samples/sec and the samples are applied to an ideal rectangular LPF with cut - off frequency of 1100 Hz, then the output of the filter contains

only 800 Hz component.

800 Hz and 900 Hz components.

800 Hz and 1000 Hz components.

800 Hz, 900 Hz and 1000 Hz components.
