a. Sketch the trapezoidal spectrum P (f) =
b. By appropriate sketches, show that it satisfies Nyquist's pulse-shaping criterion.
Design an active low pass filter with a cutoff of 10kHz or more by more than 30db and have the pass band gain positive that does not deviate from 20db by more than 3 db. The pass band frequncy need is 800Hz and below.
Use gate equivalences to convert the circuit attached into a five level circuit containing only NOR gates and a minimum number of inverters. (Assume the inputs are available only in uncomplemented form.)
A 100 V power supply has a series limmitin restor of 100 k ohms connected to its output. draw the norton equivalent cirtuit for the power supply. explain why the norton equivalent circuit you drew approximates an ideal current source
Consider the circuit where the value of the inductor is 1H, the initial current in the inductor is iL(0)=-1A and the input source is Vs(t) = 2[u(t)-u(t-1)] and plot the corresponding current in the inductor iL(t) for all times.
Find the operating point ofeach diode to at least four significant figures using the iterativemethod and the value Vt = 25mV. This problem is more difficult thanthose presented in the text because the iteration must proceed over three elements
A pn junction may be formed by depositing a single crystal film of uniformly doped p-silicon onto a substrate that has been doped n-type. The substrate is 500um thick, and the film is 20um thick. The substrate has a 5 ohm-cm resistivity.
create a 512-length signal by using the rand command, then low-pass filter the signal with the filter h=1/2[1 1] to bandlimit the function, which can be represented with by the command filter.m with b1=b2=1/2, and a1=1
How would you know a system is linear by just looking at its input/output characteristic graph And what does the sensitivity of a sensor tells us about the sensor
I have an algorithm need to be simulated in ns2/ns3, the algorithm is based on vehicular ad hoc network. The objective of the algorithm is predict the next AP availability and capacity in VANET scenario.
the Mars Rover Spirit got stuck in the Martian sand. The wheels kept slipping. Attempts to free it were futile. Discuss the type of actuator in this case. Can you suggest any improvements in the actuator that would have prevented this unfortunate ..
An 80KHz sinusoidal voltage has zero phase angle and a maximum amplitude of 20 mV. When this voltage is applied across the terminals of a capacitor, the resulting steady state current has a maximum amplitude of 0.7 mA.
If it is possible to determine whether a circuit is in resonance given only the RMS values, explain how it could be done. If it is not possible, explain what further information you would have to have.
