About 10,000 Btus of heat input are required for an electric utility to produce 1 kilowatt-hour of electrical energy. How many metric tons of coal must be supplied each hour to provide the input heat requirements for a 1,000-megawatt power plant?
a- The adjustability of the potentiometer can be used to obtain an adjustable output voltage b- Both power supplies must be used so that the adjustable voltage can have both positive and negative values
Given a real-time digital signal processing system, how do the sampling frequency and the number of bits used in performing the analog-to-digital conversion of an analog input signal impact the design and performance of the system
Calculate Is and the current I for V = 700 mV for a pn junction for which Na = 1017 / cm³, Nd = 1016 / cm³, A = 200 µm², ni = 1.5 x 10^10 / cm³, Lp = 5 µm, Ln = 10 µm, Dp = 10 cm² / s, and Dn = 18 cm² / s
How would you determine whether a given function, f(t), had finite or infinite energy. Give an example of a function with finite energy and one with infinite energy.
consider a system with a 0.1mw transmit power unit gain for the transmit and receive antennas operating at 50 mhz carrier frequency with a 100khz bandwidth.the system operates in a suburban environment.
A variant of the binary symmetric communication channel described in class is called a binary erasure channel. The transmitter sends a ‘0' or ‘1,' but at the receiver there are three possibilities: a ‘0' or ‘1' or ‘undecided bit..
design a PCM system that converts an analog signal to digital signal. specify the sampling frequency and the number of quantization levels you pick. the signal to quantization noise ratio must be higher than 57 dB.
A 100-Ohm lossless transmission line is to be matched to a load with impedance ZL = 120 - j80 Ohm using a short-circuited stub. Use the Smith chart to determine: (a) the standing wave ratio, (b) the shortest distance from the load to the location ..
derive and determine the transmission reflection coefficients for a particle traveling with an energy (a) 2ev and (b) 20ev. If the block is given infinite potential and the length is expanded to 1m,(c) what would be the transmission and reflection..
Write an assembly language program to turn the stepper motor. Start a new project. Set bits 1 to 4 of PORT P ($25A) to 1 (output direction) Do not set bits 0, and 5-7, setting these bits may produce unexpected results.
An 8-bit DAC outputs a value of 9.961 V when the input is FF (hexadecimal). What is the output when the input is 5A (hexadecimal)
Looking at a sine wave, describe how the ROM in a DDS could use only one-fourth of the memory locations to store the sine wave look-up table. Discuss how narrowing the bandwidth of a circuit affects the noise level.
