The upper side frequency of an AM signal is 603 KHz. If the carrier frequency is 600 KHz, what is the intelligence frequency
Consider an LTI(linear,time-invariant) system with input x(t) and output y(t). Suppose you know(measure) the step response, tha is , for x(t) =u(t), you know that y(t) = 2e^(-0.5t)*u(t). Find the output for the following different inputs
A 3-phase, 5 MVA, 11 kV, 60 Hz synchronous machine has a synchronous reactance of 10 Ohms per phase and has negligible stator resistance. The machine is connected to the 11 kV, 60 Hz bus and is operated as a synchronous condenser
The boards have a weight of 40 lb, centered G. Determine the smallest angle Theta required for the man to support these boards, neglecting the man's weight and the friction between his shoes and the floor.
The unit impulse response of the system - Find the first three terms of the causal signal - calculate the electric field E from Gauss law and then obtain the potential at the center of the charge distribution
Consider the discrete-time sinusoid given by x[n] = A cos(ω n+ φ), where x[n] may or may not be periodic. For it tobe periodic with a period of N, it must satisfy x[n] = x[n + N] forall integers n.
The electron distribution in the conduction band peaks at energies close to the conduction band edge. Using the Boltzmann approximation, find the energy in the conduction band (as a function of temperature) at which the electron density peaks
An 11000V/230 V. 50 Hz, single phase, core type transformer has a core section 25cm X 25cm. Allowing for a space factor of 0.9, find the suitable number of primary and secondary turns, if the flux density is not to exceed 1.2 T.
the noise produced by a resistor is to be amplified by a noiseless amplifier having a voltage gain of 75 and a
Define X and Y to be two discrete random variables whose joint probability mass function is given as follows: P(X = m, Y = n) = e^7*4^m*3^n?m / m!(n m)! , for m = 0, 1, . . . , n and n = 0, 1, 2, . . . , while P(X = m, Y = n) = 0
Determine (a)secondary voltage; (b)secondary current; (c)primary current; (d)input impedance at primary terminals of transformer; (e)active, reactive, and apparent power input to transformer.
A large reel of paper installed at the end of a paper machinehas a diameter of 1.8m, a length of 5.6m and a moment of inertia of4500 kg-m2. It is driven by a directly coupled,variable-speed DC motor turning at 120 rpm. The paper is kept undera con..
A bidirectional shift register is one in which the datacan be shifted either left or right. It can be implemented by usinggate logic that enables the transfer of a data bit from one stageto the next stage to the right or to the left, depending on ..
