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.

7-22 Abasehand signal with frequency components from near de to 15 kHz frequency modulates a 200-kHz carrier, and the frequency deviation is +3 kHz. The signal is applied as the input to a cascade of two frequency triplers and one frequency doubler. Determine the output (a) center fre- quency, (b) frequency deviation, and (c) deviation ratio.
what happens when the modulation order is increased for a modulated signal?
2. The analog signal shown in the following figure is to be delta modulated. The sampling period and the step size are indicated by the grid on the figure. Draw the staircase function that follows the signal as closely as possible and write down the delta modulation output.
