Hexadecimal is of use in IT because (1) It is a compact system (e.g. only 3 digits represent the number 986) (2) As 16 are a power of 2 it turns out to be quite easy to conv
Q. What is Barkhausen criterion? Why is the value of Ab kept slightly greater than 1? The condition |Ab| = 1 is called the Barkhausen criterion. It implies that when |Ab| = 1,
1. Find the Nyquist rate for the following signals: (a) x(t) = 5 sin 3000Πt cos 4000Πt (b) A binary channel with bit rate 36000 bps is available for PCM voice transmission.
