Exercise 6: Consider an audio signal with an amplitude that ranges over the interval [-10,10] and with spectral components limited to the frequency band of 300 Hz to 3300 Hz. The signal is sampled at a rate of 8000 samples/second and used to generate a PCM signal. The signal-to-quantization- noise ratio (SQNR) is required to be maintained at 43.9 dB a) What is the minimum number of uniform quantization levels needed, and what is the minimum number...

Given an input voltage of 120VAC (RMS) +/- 1% mains voltage with 60 Hz frequency (plugged into your wall), design a rectifier circuit that outputs +9V and -5V (account for diode voltage drop). The output voltages should be within +/- 5% of their specification (including peak-peak voltage ripple) with a load of up to 40 mA on the +9V supply and 20 mA on the -5V supply. (6 points) Show circuit diagram of design. For transformer, simply specify turns ratio(s)....
