Shannon's formula for capacity (in bits/s) for a particular bandwidth was based on only one other parameter. What was it? We commonly equalize two voice channel impairments. What are they and what does equalization do? Why do higher speed analog voice channel modems use a center tone frequency around 1700-1800 Hz?
A voltage of 60cos(4πt) V appears across the terminals of a 3mF capacitor. Calculate the current through the capacitor and the energy stored in it from t=0 to t=0.125 seconds.
Three two-input "AND" gates have their outputs connected to an "OR" gate. The first "AND" gate has each of its inputs at logic HIGH level. The second "AND" gate has each of it's inputs at logic LOW level.
Show that a Johnson counter with n flip-flops produces a sequence of 2n states. List the 10 states produced with five flip-flops and the boolean terms of each of the 10 AND gate outputs.
Use electric circuit analysis techniques and Laplace methods to find the charge, q(t), on the capacitor as a function of time. The switch is closed at t = 0 and the initial voltage V0 on the capacitor is 5 Volts.
On a spacecraft two engines fire for a time of 541 s. One gives the craft an acceleration in the x direction of ax = 4.90 m/s2, while the other produces an acceleration in the y direction of ay = 7.60 m/s2.
What is the area in circular mils of an aluminum conductor that is 80 ft long with a resistance of 2.5Ω? - What is its diameter in inches?
Derive the circuits for a three-bit parity generator and four-bit parity checker using an odd parity bit.
What is the resistivity of the wire? conductivity? Using the original dimensions of the wire, how much current can you pass through the wire until a 5V signal is degraded 5% or more?
The voltage drops across three resistors in series are measured 10V, 15V, and 25V. If the largest resistor is 47 ohms, what is the value of the smallest resistor?
