Question 3
A 1 MHz clock signal is applied to a J-K Flip Flop with J = K = 1. What is the frequency of the Flip-Flop O/P signal?
Question 6
A 10-bit DAC hasa step size of 10mV. What is its Full scale O/P voltage and the percentage resolution?
Question 9
In Digital Filters, how many interpolated data points are inserted between samples when performing 4X over sampling?
Question 10
A PAM source generates four symbols 3 V, 1 V, -1 V and —3 V with probability of p(3) = 0.2, p(1) = 0.3, p(-1) = 0.3, p(—3) = 0.2 respectively. The variance for this source will be
