A DSP system contains an anti-aliasing second-order Butterworth low-pass filter (LPF) with a cutoff frequency of 3.4KHZ, followed by a sample and hold circuit with a sampling frequency of 8KHZ, then terminated by an analog-to-digital converter (ADC) as a coding stage. Let the analog frequency at its input is 2KHZ. 1) Calculate percentage level of aliasing %. 2) Modify the order of the given anti-aliasing Butterworth LPF to reduce the aliasing level percentage to less than 12%.

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. Processing center Cable Receiver (14)
A DSP system contains an anti-aliasing second-order Butterworth low-pass filter (LPF) with a cutoff frequency of 3.4KHZ, followed by a sample and hold circuit with a sampling frequency of SKHZ, then terminated by an analog-to-digital converter (ADC) as a coding stage.
