Calculate Vout (f0), Vout (3f0), Vout(5f0), and Vout(7f0) of the frequency spectrum of a triangle wave(A = 10 V and T = 1 ms) passed through a low-pass R-C filter (R = 10 k-ohm and C =5 nF). Using Matlab simulator sketch the input and output waveforms resulting from the first 4 harmonics (for simplicity ignore the phase shift experienced by each harmonic)
Prepare an Excel graph showing the individual components and summated resultant waveform of the odd harmonic series resulting in an approximate square wave.
1. Give a summary of the article, what is the basic concept and the key technology. 2. What are the differences, advantages and disadvantages of the proposed technology compared to conventional MOSFETs and BJTs.
In a typical mobile communications base station (or cell site), a radio frequency (RF) signal is amplified in the base station and then sent (over cable) to the antennas at the top of the tower.
Determining how to use the function fft to find the DFT coefficients X[k] of x[n] in Matlab. Also, how would you plot the magnitude of X[k] in Matlab?
A single-phase half-wave rectifier is fed with a triangular signal with period 2 . The maximum positive and negative amplitudes are ± 12 V rms. determine: a) The value of the DC output voltage. b) The percentage of curly
b) find nonhomogeneous solution with method of undetermined coefficient with constants evaluated c) combine homogeneous soluton with nonhomogeneous solution to form the general solution calculate the unknown constant in homogeneous part
A circular loop of radius a is located in the y-z plane center at the origin in the presence of a uniform B field pointed in the +x direction. At t=0 the loop is rotated counter clockwise with radial frequency about the z-axis.
A circuit is needed to display a 4-bit value on the LEDs of the logic designer. This value can come from two different sources. Design a circuit using four 2-to-1 multiplexers to select which of the two values to display on the LEDs.
Design a circuit that might be used as a trigger for a night-light. You are given a photoresistor whose resistance changes from 5k when inside a lighted room to 30k in a dark room. Design a voltage divider circuit that will provide a 3V
A 9.1 V zener diode exhibits its nominal voltage at a test current of 29 mA. At this current the incremental resistance is specified as 5 ?. The zener knee current is 1 mA. i. The zener knee voltage, VZK. ii. The zener voltage at a current of 10 ..
A constellation diagram has two points located at (3,0) and (-3,0) on the I(in-phase)-Q(quadrature phase) plane. Find the value of peak amplitude and the type of modulation this diagram represents.
