engineering recuitment GATE ECE 2023-24 Test Series Communication Systems Pulse Modulation Pulse Code Modulation (PCM) System
A message signal having peak-to-peak value of 2 V, root mean square value of 0.1 V and bandwidth of 5 kHz is sampled and fed to a pulse code modulation (PCM) system that uses a uniform quantizer. The PCM output is transmitted over a channel that can support a maximum transmission rate of 50 kbps. Assuming that the quantization error is uniformly distributed, the maximum signal to quantization nose ratio that can be obtained by the PCM system (rounded off to two decimal places) is _____
Enter numerical value using the virtual keypad. Round off where necessary.
