How is the induced voltage of a separately excited DC generator affected if .a-the speed increase ? b- the excitation current is reduced?
RC series circuit c=10,r=1,vs=15 and intial capictor charge q(0)=0.01. write standard form of the diffierential equations which describe the capictors charge q(t) t>0, obtain integration factor u(t),and determine general solution for q(t)
Write a short technical report on Frequency Division Multiplexing
When we shift left we fill in the 0's so that a shift of one left gives x1 = 0110 and x2 = 1110. When we shift right we fill with the sign bit, so that a shift of one right gives x1 = 1011 and x2 = 0011 and a shift of two right gives x1 = 1110 and..
A bandpass filter with a center frequency of 6kHz, a 3dB banwidth of 1 kHz, and a 50 dB bandwidth of 2kHz is connected to a signal generator that outputs a one volt square wave at a frequency of 2kHz. A spectrum analyzer is connected to the filter..
a) Design a minimum two-level NOR-gate network to realize the above function. b) Design a minimum three-level NOR-gate network to realize the above function.
A signal y(t) is defined as y(t) = box(t/1.1) * box(t/0.9) * box(t/0.8) * box(t/1.2) where * denotes convolution and the signal box(t) is box(t) = u(t+0.5)-u(t-0.5). -Determine y(1.0) -Determine max(y(t)) -Determine the definite integral of y(t) o..
The gradient of a function F(x,y,z), written as or grad F, is found as where is the unit vector in the x-direction. is the unit vector in the x-direction, and Ls the unit vector in the x-direction. What is when F = 2x + 3y2z
There are to be 15 states, and the device for utilization is a 22v10 chip using 8 flip flops internal to the device. The outputs are 8 LEDs and a secondary output Z that is a 1 if states 10,11,12,13 are active.
The power amplifier in a home theater amplifier has an output power of 200 watts. Assuming a Class B amplifier with the maximum theoretical efficiency is used, find the DC power delivered to the amplifier.
A transformer has 100 turns on the primary (terminals 1-1') and 200 turns on the secondary (terminals 2-2'). A current in the primary causes a magnetic flux, which links all turns of both the primary and the secondary.
Maximum value of frequency deviation is fixed at 75 kHz for commercial broadcasting by radio. Modulation frequency W = 15 kHz, then find the transmission bandwidth of signal and deviation ratio.
an induction motor when connected in delta and started direct on line produces a starting torque of 60Nm and consumes 80A. if the same motor is started using the soft start equipment with the voltage set at 0.8 of the line
