It is desired to set up a central station for simultaneous monitoring of the electrocardiograms (ECGS) of 10hospital patients. The data from the 10patients are broughtto a processing center over wires and are sampled, quantized, binary-coded, and time-division-multiplexed. The multiplexed data are now transmitted to the monitoring station (Fig. P6.2-5). The ECG signal bandwidth is 100 Hz. The maximum acceptable error in sample amplitudes is 0.25% of the peak signal amplitude. The sampling rate must be at least twice the Nyquist rate. Determine the minimum cable bandwidth needed to transmit these data.
