engineering recuitment GATE ECE 2023-24 Test Series Communication Systems Pulse Modulation Pulse Code Modulation (PCM) System
An audio signal \(m\left( t \right) = 3\cos \left( {100\pi t} \right) + 3\cos \left( {1400\pi t} \right) + 2\cos \left( {2000\pi t} \right)V\) is sent using a 10 bit PCM system the bandwidth required and the quantization step size are
1
10 KHz and 9.16 mV
2
5 KHz and 5.1 mV
3
10 KHz and 7.3 mV
4
5 KHz and 4.2 mV
