Assuming a continuous signal is given as
Sampled at a rate of 8,000 Hz,
a. Sketch the spectrum of the sampled signal up to 20 kHz;
b. Sketch the recovered analog signal spectrum if an ideal low pass filter with a cutoff frequency of 4 kHz is used to filter the sampled signal in order to recover the original signal;
c. Determine the frequency/frequencies of aliasing noise.
Choose a suitable sampling period and use Euler's forward rectangular rule toobtain an approximating discrete-time controller K(z).
An intercom system has a 13 kHz annoying whistle with amplitude of 20% of a typical voice signal. Assume that a typical voice signal has a frequency of 3 kHz and the intercom's output for a typical voice level has amplitude of 10V.
Locate and specify an appropriate sensor if it is to operate at 120 vac as an input to a PLC. Create the ladder diagram program to accomplish the specified control.
Describe how a dielectric material responds to an alternating electric field. Describe how the permittivity might change with time for a polymer material like the paint as it dries and explain how this measurement could be used to find when the pa..
A semiconductor company has the following costs associated with Product X: - Fixed cost of $1B ($1,000,000,000) - Die cost of $6 at a die yield of 50% - Testing and packaging cost of $3 per die - A final test yield of 90% with a product volume of 500..
Given the 16-bit value 1010 0101 1001 1000, what operation must be performed, and what operand is needed, in order to (a) set the most significant 8 bits to 1s (b) clear the bits in even positions (the left most bit is 15 andthe right most bit is 0) ..
a) Construct 4 to 16 line decoder with 3 to 8 linedecoders adn additional circuit as appropriate show using block diagram. b)Design a 5x1 using 3x1 muxes and any additional entities needed.
The Y values correspond to an X domain ranging from -3 to 6 with a step size of 0.01. The program must use a function that performs the numerical differentiation method described below to calculate the derivative of the input data and write the re..
Describe the operation of the transmission gate. Consider the source and drain terminals of both the NMOS and PMOS devices. Why not use two NMOS devices Does it pass analog or digital signals
What is the channel capacity for a channel with a 300 Hz bandwidth and as S/N = 3? 2nd problem: Given a channel with a 50 kHz bandwidth and a S/N = 127, determine:
A three-phase generator rated 480 V, 400 kVA is connected to a three-phase transformer rated 3.2 kV Y-grounded/480 V, 200 kVA, with reactance of 10%. The transformer is 100% loaded based on its rating at 0.9 pf leading.
A network has an input impedance of 120+100j Ohm what is the capacitance that should be placed in parallel with the network to provide an input impadance with: a) Zero Reactance at w=1000 rad/s b) Zero Reactance at w=2000 rad/s
