Question
1. A system samples a sinusoid of frequency 740 Hz at a rate of 200 Hz and writes the sampled signal to its output without further modification. Determine the frequency that the sampling system will generate in its output.
a. 740
b. 40
c. 140
d. 60
a. 65, 95, 165, 195, 510, 540
b. 65, 95, 150, 180, 310, 340
c. 65, 95, 175, 245, 315, 365
d. 65, 95, 175, 245, 365, 395
3.A signal has a spectrum from 0 to 325 Hz, as shown below. It is sampled at a rate of 430 Hz. Find the region of the baseband spectrum that will become corrupted and unrecoverable even if an ideal
2. A signal consists of only two sinusoids, one of 65 Hz and one of 95 Hz. This signal is sampled at a rate of 245 Hz. Find the first six positive frequencies that will be present in the replicated spectrum.Explanation / Answer
