Current and average power delivered to the load
A load has a 20 ohm resistor and a 4 henry inductor connected in series. It is connected to a power source with v(t)= 100cos50t, connected in series to the load. What is the impedance, the current, and the average power delivered to the load using the phasor transform method.
Why can't a video signal such as an NTSC analog television signal be transmitted over a two km length of loaded twisted pair cable with a frequency range 300 Hz to 3,400 Hz? What is the bandwidth occupied by an NTSC video signal?
Using the table, what is the byte stored at address 2F? Using the table, what is the byte stored at address 33?
Compute the inverse Fourier transform for X(ω) = cos 4ω. 5. A signal with the highest frequency component at 10 kHz is to be sampled. To reconstruct the signal, the sampling must be done at a minimum frequency of?
The aim of this experiment is to develop a bipolar transistor amplifier with a voltage gain of minus 25. The amplifier must accept input signals from a source impedance of 1 kW and provide an undistorted output amplitude of 5 V when driving a 560..
What RF bandwidth is required to send the data using QPSK? If the RRC filters in the transmitter and receiver are replaced with ones that have ? = 0.20, what are the new RF bandwidths in parts (a) and (b)?
In order to eliminate the cost of calling cards, the company in the above problem is considering a new policy that requires blocked callers to redial over and over until they get a trunk.
The basic column control system shown in Figure is somewhat more complicated than the basic neutralizer control system
Analysis of z transform to time domain, poles and zeros, From a given z transform X(z) = {1- z^-10}/{1 - z^-1} the discrete time domain form x(n) is deduced using complex manipulation and inverse transforms to arrive at x(n) = x(n-1) + u(n) - u(n-..
Describe the functionality of the above DFSM using transition tables. Consider that the system starts always from state B. What happens if the system will start from another state - say A?
Draw the logic diagram for the 4-bit circuit, using full adders and multiplexers. Determine the arithmetic operation performed for each of the four combinations of S and Cin: 00, 01, 10, and 11.
What is the resistivity of the wire? conductivity? Using the original dimensions of the wire, how much current can you pass through the wire until a 5V signal is degraded 5% or more?
