Error propagation. We measure flux (f) and its uncertainty (df). Convert them into magnitude (m) and its uncertainty (dm). The signal-to-noise ratio can be written as SNR=f/df. What is the magnitude uncertainty when SNR=0.1, 1, 10, and 100?
A central station is setup up for simultaneous monitoring 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 data are transmitted to the monitoring station as shown in the figure below. The bandwidth of the signal received from each patient is 200 Hz. The maximum acceptable error in sample amplitudes is 0.5% of the peak signal amplitude. The sampling rate must be at least twice the Nyquist rate. Determine the sampling rate, the number of levels, the number of bits per level and minimum cable bandwidth needed to transmit the data.
