The serial ports on two computers which use binary signaling are connected by a twisted pair cable. The cable has a flat frequency response up to 120KHz, with negligible group delay distortion. That
We use the time constant to characterize transients in electric circuits. In physics, the half-life is often used to characterize the exponential decay of physical quantities such as radioactive sub
Design a simple BJT amplifier circuit for receiving the over-the-air HDTV signals. The circuit should have a voltage gain of 10-100, assuming your signal source (antenna) is connected to amp through
A clever student notices that a high constant loop gain would make the PLL converge in frequency and phase. Rather than use an amplifier with infinite gain the student decides to just use an unstabl
Write a program to do the following: Declare a 4x4 2D integer array, Initialize the contents of the array to random numbers using rand() , Print the contents of the array, Prompt the user to enter a
Electrons in silicon carbide have a mobility of 1000 cm^2/V-sec. At what value of the electric field do the electrons reach a velocity of 3 X 10^7 cm/s Assume that the movility is constant and indep
Calculate the electron and hole densities in an n-type silicon wafer (Nd=10^17 cm^-3) illuminated uniformly with 100 mW/cm^2 of red light (Eph = 1.8 eV). The absorption absorption coefficient of red
A 1 W power source is connected to the input of a directional coupler with C=20 dB, D=35 dB, and an insertion loss of 0.5 dB. Find the output powers (in dBm) at the through, coupled, and isolated po
Given a two-dimensional array named number of three rows and four columns of type int, write the single code statement that will both declare and initialize the array such that the first row is init
A lighting load operates from a 208-V 60-Hz supply and is rated 1.0 kW with a power factor of 0.9 lagging. A 40-µF capacitor is connected in parallel with this load. Calculate the total power
Write a Matlab program to calculate the electric field due to a line of charge of length 1m. a) Describe the line of charge as a collection of point charges centered on the z-axis. Calculate the elect
A binary waveform of 53000 bits/sec is converted into an 8192 level waveform that is passed through a channel with a raised cosine-rolloff filter characteristic with r = 0.33. The channel bandwidth
A binary waveform of 53000 bits/sec is converted into an 8192 level waveform that is passed through a channel with a raised cosine-rolloff filter characteristic. The channel has a conditioned (equal
A given device has been determined that it attenuates 4.8dB in power from its input terminal to its output terminal. What is the output power in watts if a 150-W input has been launched into a syste
The detector will take in numbers from 1510 to 010 encoded in binary labeled [N3:N0] with N3 being the most significant bit. The output will be asserted when the decimal value of the input is a prim
A signal is bandlimited to 20kHz. The band between 16 and 20 kHz is corrupted by noise such that the information is unrecoverable. Determine the analog lowpass filter maximum frequency to eliminate
A particular intrinsic semiconductor has a resistivity of 50 -cm at T=300 K and 5 - cm at T=330 K. Neglecting the change in mobility and effective density of states with temperature, determine the b
A 20V voltmeter with a sensitivity of 10,000 ohms / volt rating and a 5A ammeter are used to measure the power being dissipated in a dc circuit. The voltmeter reads 13V and the ammeter 2.1A.
If a circuit is comprised of a load and multiple switches wired in series with the load and the load is operating, is it possible that one or more of the switches is in the open position
