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

|(ECGS) of 10 hospital patients. The data from the 10 patients are brought to a processing center over
wires and are sampled, quantized, binary-coded, and time-division-multiplexed. The multiplexed
