What is the Laplace Transform of cosh(at)?

If the inverse Laplace transform of F(s) is f(t), what is the inverse Laplace transform of F(s/a)?

Which of the following transistor connections has the highest input impedance?

A telephone exchange has 9,000 subscribers. If the number of calls originating at peak time is 10,000 in one hour, the calling rate is

What is the term used to describe the response of a system when the input is zero?

Let y(t) = p(t) * δ(t). The function y(t) is time shifted to the left by t_o. The resultant function is:

For a stable linear time-invariant (LTI) system, the region of convergence (ROC) should include the:

A continuous-time periodic signal x(t), having a period T, is convolved with itself. Then the resulting signal is:

Two systems with impulse responses h₁(t) and h₂(t) are connected in cascade. Then the overall impulse response of the cascaded system is given by

For the given signal,

x(t) = sin(t) + cos(t) + sin(t)·cos(t)

Find the even, x_e(t), and odd, x_o(t), parts of the signal.
