A nolinear distortion results in the generation of frequencies in the output that are not present in the input. If the dynamic curve can be represented by ic = Aib + B(ib^2), and if the input signal is given by ib= I1 cos w1t + I2 cos W2t show that the output will contain a dc term and sinusodial terms of frequency w1,w2,2w1,w1 + w2, and w1 - w2.
A 600V, dc shunt motor has an armature and field resistance of 1.5 ohm and 600 ohm, respectively. When the motor runs unloaded, the line current is 3A, and the speed is 1000 rpm.
The manufacturer of a 9V dry-cell flash light battery says that the battery will deliver 20mA for 80 continuous hours. During that time the voltage will drop from 9V to 6V.Assuming the drop in voltage is linear with time.
(1) After writing the equations for mesh analysis, what parameters will be calculated How can the results be used to determine the branch currents (2) When working with Thevenin's, list the steps for solving for Vth and Rth.
a) If the excitation voltage E0 is equal to the terminla voltage ( 4kV ), what is the maximum real power which the motor can deliver without losing synchronism b) What is the rotor pole shift in electrical degrees, corresponding to the nominal loa..
1. What is Miller capacitance What is its role in High frequency amplifier design Label all the involved variables in the Figure below and derive an expression for the Miller effect capacitances (input and output).
The base width of a npn BJT at a temperature of 300K is 4μm. If the time it takes for an electron to diffuse a distance d is t=d2/Dn, where D is the diffusion coefficient.Calculate α and ß for this BJT. Assume typical electron mobilities and the w..
What bit pattern (after you remove the beginning and ending flags and any stuffed bits) will the receiver pass on for higher level processing?
A half-wave rectifier circuit with a 1-k ohm load operates from a 120-V (rms) 60-Hz household supply through a 10-to-1 step-down transformer. It uses a silicon diode that can be modeled to have a 0.7-V drop for any current.
Using the symbols we've learned in class (standard symbols used universally), draw a schematic showing the circuit of a 12-V car battery (represented as a voltage source connected to a light bulb (represented as a resistor).
Write a script that determines whether an amino acid is going to bind to a certain molecule. It is know that the first region (1-5) of the molecule binds strongly to amino acids A, C, I, L, Y and E, and weakly to W, S, M, G, and K.
Design a circuit that will display the decimal numbers that are less than 60 by using two 7-segment displays. The number 60 should be displayed as 00. Use the least amount of IC's as possible.
What would the effect of boundaries be on the diffusivity of a substance (e.g., if you have diffusion of a substance in a pipe, what would the effect of the pipe's walls be on the diffusivity
