A 4-bit shift register is shifted six times to the fight. If the initial content of the register is 1101, find the content of the register after each shift if the serial input is 101101.
What is the net number of electrons per second that pass through the cross-section of a wire carrying 5 A of dc current The current now is due to electrons, and the magnitude of the charge of each electron is 1.60×10?19 C.
What is the attenuation per octave between 1 kHz and 10 kHz? What is the increase in attenuation between 5 kHz and 10 kHz?
The manufacturer's data sheet for a 26-kV, 750-MVA 60-Hz three-phase synchronous generator indicates that it has a synchronous reactance Xs = 2.04 and a leakage reactance Xal = 0.18, both in per unit on the generator base. Calculate
1. We consider a Rayleigh fading signal. Suppose that a single branch receiver has a 10% chance of being 5 dB below a certain SNR threshold γo.
Lcd code microcontroller: lcd write the code to perform the folling tasks: interface with lcd controller initialize the lcd clean the lcd initially display numbers and letters on lcd position the cussor within a non move to the second now of lcd subm..
Consider a pressure relief system. If consists of two values in parallel and achieves an availability of 0.95 when the valves are tested on a staggered basis, each valve being tested every 4 months. Estimate the failure rate of the values.
MOSFET Amplier Sketch the 4-resistor bias network for an amplier with an n-channel enhancement-mode MOSFET, with R1 = 1Mohm ; R2 = 1:5Mohm ; RD = 75kohm ; Rs = 39kohm ; K = 25microA/V2 ; VDD = 10V and Vto = 1V.
A radio receiver has antenna noise temperature of 3000 K and equivalent noise temperature of 7000 K for its feeder and amplifier cascade. It requires Eb/No = 15 dB to provide Probability of error of 10^-15 (using BPSK).
Consider a 4-PAM system with Gray mapping. Evaluate the exact bit error probability. Hint: Consider the bit error probability for the first and second bit separately, and then average over the two bit error probabilities. To find the error probab..
Given the spectrum X(f) of an analog signal x(t), sketch the spectrum of its sampled version x[n], assuming a sampling rate of 50, 40, and 30 Hz. (a) X(f) = rect(f/40) (b) X(f) = tri(f/20)
Bandwidth, In a given communications system, one signaling element is used to represent 64 bits. The required data rate is 1.789 Mbps.
You have a shortwave AM receiver (just an AM receiver that has the capability to receive signals in the FM frequency band) that receives an NBFM voice signal at some carrier frequency. You notice, however, that while the signal strength is maximiz..
