A digital communication system transmits one of the three values -1,0,1. A channel adds noise to cause the decoder to sometimes make an error. The error rates are 12.5% if a -1 is transmitted, 75% if a 0 is transmitted, and 12.5% if a 1 is transmitted. If the probabilities for the various symbols being transmitted are P [ - l ] = P[l] = 1/4 and P[0] = 1/2, find the probability of error. Repeat the problem if P[-1] = P[0] = P[l]
Characteristics of a filter, A filter has the following characteristics: Attenuation = 3.0 dB from 0 Hz to 2 kHz. From 2 kHz to 20 kHz attenuation increases from 3 dB to 23 dB in a straight line when plotted on axes of power in decibels (vertical a..
A majority gate returns a true output if more than half of the inputs are true. So, a 3-input majority gate outputs a ‘1' if at least two of its inputs are ‘1'. A minority gate generates the complement, that is it outputs ‘0' if at least two of th..
Compare the capacities of the fiber and conducting cables. How many of the conducting cables are required to equal the capacity of the fiber cable.
Design a DC current source to meet the following specifications: - Current source value: 100 u-amps +/- 1% (over all possible load and supply voltage conditions). - Output resistance: >20 Mohms. - Available DC voltage sources are bipolar and range fr..
Use the immediate addressing mode to add four to each value that is loaded to accumulator. Store the results in Locations 13-15. Let's assume that in Locations 10-12 we have the values 5, 6, and 7. After executing your code, the values in Location..
Power Systems Theory Definitions and Formulas, Define, (a) The fault level of a system or unit in a system, (b) base MVA
b)If the calculator produces three digit random numbers that are uniformly distributed between 0.000 and 0.999, find the variance of the sample mean. c) How large should the sample size be in order to obtain a sample mean whose standard deviation i..
How do you draw the standard form simulation diagram given a higher-order differential equation; and how to make adjustments if the output must be put in the state equation form, y=Cx+Du.
The energy (power) in Watts in an electrical circuit is described by P = VI, where V is volts and I is current
Using the Internet, a magazine, or a provided list of memory modules, determine the exact part numbers and quantities of memory modules that you would buy. List them with the location of where you obtained the information.
Instead of recreating the design every time we change the instruction ROM, we want to have a way to change the instructions while the system is running. Discuss how the UART can be used to fill an instruction RAM instead
Write down the expression for the frequency-dependent open-loop gain of an operational amplifier. Sketch the magnitude of the open-loop gain of an operational amplifier as a function of frequency. Explain what is meant by a `single-lag' response o..
