An image uses $$512\, \times \,512$$ picture elements. Each of the picture elements can take any of the 8 distinguishable intersity levels. The maximum entropy in the above image will be

In a BPSK signal detector, the local oscillator has a fixed phase error of 20⁰. This phase error deteriorates the SNR at the output by a factor of

A system is characterized by the following state-space equations:

a) Find the transfer function of the system

b) Compute the state-transition matrix/p>

a) Solve the state equation for a unit-step input under zero initial conditions

The transfer function of a simple RC network functioning as a controller is: $${G_c}(s) = {{s + {z_1}} \over {s + {p_1}}}$$

The condition for the RC network to act as a phase lead controller is:
