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.
In use, an appropriate bias voltage is applied between the two bases, with B2 made positive with respect to B1. Because the N-type bar is resistive, a relatively small current will
Q. Find the exponential form of the Fourier series of the periodic signal given in Figure. Also determine the resulting series if T = 2τ .
Critical Rate of Rise of Voltage It depends on the junction temperature higher the junction temperature lower the critical rate of rise of voltage. It is also known as
Q. Consider a reverse-biased diode with a source voltage VB in series with a load resistance RL. Write the KVL equation for the circuit.
Hexadecimal Number System Similar to octal number hexadecimal number system is also used to represent long binary numbers in smaller form. In microprocessor we use hexad
In a 3-stage continuous ultrafiltration process, a solution is concentrated from 5 gm/Liter to 50 gm/Liter of protein. The final retentate is to have a flow rate of 1000 L/hr. The
Time constant at decay of current In decay of current by an inductor, a method to find values of time constant similar as in rise of current through an inductor. The difference
Switching Characteristics During Turn off The techniques used for turning off a thyristor is known as commutation techniques. A thyristor can be can be turn off by reducin
Given the INPUT: • An array of 64-bit unsigned integer elements stored in the memory starting at a known location SOURCE. • The size of the array (i.e., number of elements) stored
Q. Explain working of Single-Phase Induction Motors? For reasons of simplicity and cost, a single-phase power supply is universally preferred for fractional-horsepower motors.
