For the following questions answer them individually
In case of which of the following, an increase on the modulation index leads to increase in bandwidth
Four voice signals, each limited to 4 kHz and sampled at Nyquist rate, are converted into binary PCM signal using 256 quantisation levels. The bit transmission rate for the time division multiplexing signal will be
The output of a circular convolution performed on two signals $$x_{1}(n) = {\underline{2}, 1, 2, 1}$$ and $$x_{2}(n) = {\underline{1}, 2, 3, 4}$$ is
Whenusing a sequential code to design a combinational logic in VHDL,if complete truth table is not defined, the synthesis tool will implement a which is not required.
24V, 600mW Zeneris to be used for providing a 24V stabilized supply to a variable load. Assume that for proper Zener action, a minimum of 10 mA must flow through the Zener. If the input voltage is 32V, what would be the value of R and the maximum load current?
