under insolation conditions 500 W/m^2 (direct sunlight), and 10% solar cell efficiency, calculate the area required for a photovoltaic array capable of running an electric vehicle driven by a single 40 hp motor for 3 hours at half power
Draw the logic diagram for the following Boolean expressions. The diagram should correspond exactly to the equation. Assume that the complements of the inputs are not available. a.) XYZ+X'Y'+X'Y'
The woofer can be modeled as a series R-L low pass filter. Suppose that a given woofer has an inductance of 750 micron Hertz and a resistance of 4 Ohms. At what frequncy (in Hertz) does its frequncy response
Design a 4-bit circuit for 2s-complement, base on the formula below, using only inverters, 2 input AND gates and 2 input OR gates. Design your circuit to be as fast as possible. What is the worst-case propagation delay for this circuit
A 78oham lossless planar line was designed but did not meet a requirement. What fraction of the widths of the strip should be added or removed to get the characteristic impedance of 75oham
a) If the internal resistance of a voltmeter is 100x bigger than the output impedance of a circuit, what is the loading error b) If the internal resistance of an ammeter is 10x smaller than the output impedance of a circuit
Digital Communications, Order the following modulation types in terms of spectral efficiency (best to worse) and explain
Design a counter to count even numbers between 0 and 15. Therefore states will be 0 -> 2 -> 4 -> 6 -> 8 -> 10 -> 12 -> 14 -> 0. If any unused state is encountered bewteen 0 and 7, then the counter should go back to initial state 0.
Drift velocity the actual (physical) velocity of electrons along the wire. Transmission velocity the rate at which information can be transmitted electronically using conducing wires. How is it possible that the transmission velocity is so much faste..
If designing a computer configuration for use as a workstation for one specific application, what aspects of the software need to be considered as part of the design process?
A source X produces symbols A, B, C, D, and E with probabilities 0.5, 0.25, 0.125, 0.0625 and 0.0625 (a) Find the information content of X. (b) Give a fixed length code for X. Compute its efficiency. (c) Derive a Huffman code for X
Calculating peak frequency deviation and Carson's rule bandwidth, A baseband signal has a frequency range from 50 Hz to 15.0 kHz. The signal is transmitted using frequency modulation. The FM transmitter has a modulation constant of 100 kHz per vol..
Generate a sine wave signal with amplitude A=1, and frequency=0.1592Hz. Using a uniform PCM method, quantize it ot a) 8-level and b) 16-level. Plot the original signal and the quantized signals on the same axes
