O As an engineer at ASTROZ, you have a task to upgrade current television system. Before upgrading process, current system information need to be collected. As example, TV7 is a television signal (video and audio) has a bandwidth of 4.5 MHz. This signal is sampled, quantized, and binary coded to obtain a PCM signal. Determine: - 14- SULIT
i. ii. iii. SULIT (BEKC 2453) The sampling rate if the signal is to be sampled at a rate 20% above the Nyquist rate. (4 marks) The number of binary pulses required to encode each sample, if the samples are quantized into 1024 levels. (3 marks) The binary pulse rate (bits per second) of the binary-coded signal, and the minimum bandwidth required to transmit this signal. (2 marks) [25 marks]
