Q4) A black and white television picture may be viewed as consisting of approximately 3x10 elements each one of which may occupy one of 10 distinct brightness levels with equal probability. Assume the rate of transmission to be 30 picture frames per second, and the signal to noise power ratio is 30 dB. Using the channel capacity theorem, calculate the minimum bandwidth required to support the transmission of the resultant video signal.
