Consider the following signals, sketch each one of them and comment on the periodic nature:
(a) x(t) = A cos(2πf0t + θ), where A, f0, and θ are the amplitude, frequency, and phase of the signal.
(b) x(t) = ej(2πf0t+θ) , A> 0.
(c) Unit step signal u-1(t) defined by u-1(t) =
(d) Discrete-time signal x[n] = A cos(2πf0n + θ), where n is an integer.

Suppose the ambiguity function of some waveform x ( t ) of duration ζ = 1 millisecond is given by (NOTE: this is not a possible AF because it is not time-limited to
An angle-modulated signal has the form u(t) = 100 cos [2πf c t+4 sin 2πf m t ],where f c =10MHz and f m = 1 kHz. Determine the modulation index β f or β p and the transmitted s
Temperature Triggering At high temperature the leakage current of junction J 2 increases. This leakage current is collector current of tr 1 and Tr 2 . So rise in temperat
