What is the magnetic force on a square loop of current I placed in a uniformed magnetic field B with the plane of the loop perpendicular to the magnetic field? Explain
Consider a (Nt,Nr) =(4,4) MIMO channel. For the input of the channel x = [x1,x2,x3,x4] assume that each xi is drawn from a BPSK constellation with energy P. Also assume that the channel noise variance is σ2 =1
a) Plot the spectrums for the range from 0 Hz to 25000 Hz. Make sure to label the frequncies. b) sketch the recoverd analog signal spectrum if an ideal lowpass filter with a cutoff frequncey of 4.5 kHzis used to filter the sampled signal.
I have a 3.6V battery, a shottky diode with a voltage drop of 0.22V, and an LED rated at 3V and 100mA. How much resistance will I need. Do i subtract battery voltage - LED voltage and divide by current desired
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.
Consider the following MATLAB code: a = 0:(1/9000):4; % vector of time samples b = 100*a; % instantaneous frequency x = sin(4*pi*b.*a); (a) How many samples are in vector a, b, and x, respectively
Explain the difference between TDM and TDMA.
(a) Three volts is applied across a 1-cm-long semiconductor bar. The average electron drift velocity is 104 cm/s. Find the electron mobility. (b) If the electron mobility in part (a) were 800 cm2/V-s, what is the average electron drift velocity
Consider a (1;N) SIMO channel (with N > 1), represented by a N x 1 channel vector h1 with hH1 h1 = II h1 II2 = 1. Suppose that the received signal is given by x = h1s + n, where the power of the data signal s is E(IsI2)= P
Given an electronic sensor, measuring the speed and outputing it in voltages, we are asked to design this computer unit. Design an analog computer, getting the speed information from a sensor and returning speed + 3 times the acceleration value to..
A charged 100-pf capacitor has initial voltage across it of 10V. a 100kohm resistor is suddenly connected across the capacitor (at t=0) to discharge it. What is the magnitude of the instantaneous current at 20 usec?
a zener diode exhibits a constant voltage of 5.6 volts for currents greater than five times the knee current.Izk is specified to be 1 ma. the zener is to be used in the design of a shunt regulator fed from a 15 volts supply .
