Week 3 Assignment

(Subject: Instrumentation & Measurements) Hello dear, l need to answer in a short time, less than an hour.

Briefly explain why in the digital transmission of sound in radio systems, an analogue to digital converter required at the transmitter and a digital to analogue converter is required at the receiver.

NUMERICAL DATA COMMUNICATION    An analog signal in sine form is intended to be transmitted to the receiver by pulse code modulation.Given below Define the parameters and answer the questions asked from you. *Peak to peak amplitude = xxx volts *Signal frequency = xxx Hz *Medium height form factor: xxx level   1-)What should be the theoretical minimum sampling frequency for the signal to be reconstructed in the receiver without distortion? 2-) What should be the practical minimum sampling frequency for the signal to be recreated in the receiver without distortion?

An analog signal is to be coded by an ADC. The signal contains significant frequencies up to 6MHz.  The quantization error in any one sample value must be within ± 0.5% of the peak-to-peak amplitude range of the ADC. How many binary digits must each sample contain? Apply (or equate) the formulas:Δ = Xmax - Xmin / L - 1where Xmax - Xmin = peak-to-peak amplitude range (XRange)eq[n] = Δ/2 (maximum quantization noise)eq[n] = 0.005 XRange
