1. An analog information signal, whose maximum frequency is 6000Hz, is to be transmitted using a PCM system. The quantization error must not exceed the 1 % of the peak-to- peak analog signal.
(a) What is the minimum number of bits per sample or bits per PCM word that should be used in this system?
(b)What is the minimum required sampling rate, and what is the resulting bit rate?
(c)What is the PCM pulse or symbol transmission rate?
When you have a three phase short circuit of power cables laid in a trefoil formation they repel apart very dramatically. Why is this and what is happening?
