A continuous time LTI system is described by
Assuming zero initial conditions, the response y(t) of the above system for the input x(t) = e-2t u(t) is given by -
The analog signal given below is sampled by 600 samples per second
m(t) = 2 sin 480pt + 3 sin 720pt
The folding (maximum) frequency is __________ . -
In analog signal given below is sampled at such a rate that the samples of signal can be given to a collection of buffers having capacity of either 24 samples/sec. or 25 samples/sec. The sampling rate is minimum such that it fully utilizes the collection of both types of buffers m(t) = 2 sin 480pt + 3 sin 720 pt
The folding (maximum) frequency is -
For a Gaussian process, auto-correlation also implies
-
The eigen values of a skew symmetric matrix are
-
An LTI system having transfer function
and input x(t) = sin (t + 1) is in steady state. The output is sampled at a rate ωs rad/s to obtain the final output {y(k)}. Which of the following is true? -
A switch tail ring counter is made by using a single D FF. The resulting circuit is a

to be stable will be
Thus output is zero for all sampling frequencies.
