Assume that an analog audio voice-frequency (VF) telephone signal m(t) occupies a band from 300 Hz to 3000 Hz. The signal is to be converted to a PCM signal for transmission over a digital telephone system. The signal is sampled at a rate 33.3% higher than the Nyquist rate. The maximum acceptable quantizatiorn error is 2% of the peak amplitude of m(t). The quantized samples are binary coded. Find the minimum bandwidth B of a noiseless channel required to transmit...
The oscilloscope display below is connected to a sine wave of 100 Hz frequency and 4 volt amplitude, 100 us seconds/div, and 2 volts/div. What control(s) on the oscilloscope need to be adjusted to bring this signal into focus so that it displays a sine wave? The oscilloscope display below is connected to a sine wave of 150 Hz frequency , 2 ms seconds/div, and 1 volts/div. What control(s) on the oscilloscope need to be adjusted to bring this signal...
Data communication Qs A signal has a bandwidth frequency of 150 Hz and the highest frequency is 170 Hz. What is the lowest frequency of the signal? (just put the whole number. No decimal values. No units next to the number) A periodic signal completes one cycle in 0.04 second. What is the frequency? A sine wave completes 7200 cycles in one hour. What are its frequency and period? I: 50 Hz, II: 10 Hz, 0.1 seconds I: 25 Hz,...
