A buffer amplifier with a gain of 1 V/V has an input resistance of 1MΩ and an output resistance of 10Ω. It is connected between a 1-V, 100-kΩ source and a 100-Ω load. What load voltage results and what are the corresponding voltage, current, and power gains in dB?
Random variable X is Gaussian with zero mean and variance of 1. Y is defined as Y=X^5. How do I find the probability density function, mean and variance of Y
An analog system requires an antenna signal power of 100pW to meet the required detected signal-to-noise ratio. Other system parameters are given as follows: Gt(dB) =4dB determine the minimum value of the transmitter power required.
Consider a cylindrical cavity of diameter D=100 mm and depth L=50 mm whose sidewall and bottom are diffuse and gray with an emissivity of .6 and are at a uniform temperature of 1500 K. The top of the cavity is open and exposed to surrounding that ..
write a C program to toggle both PA4 and PA7 of PORTA ON and OFF, with a 1-ms delay after each toggle. Assume that clock frequency is 6.25 MHz. Write inline assembly-language code inside of the delay function.
a positive-sequence shunt admittance y= j4.4* 10-6 S/km. for this line if it has 70% shunt reactive (inductors) compensation and 40% series capacitive compensation. Half of this compensation is installed at each end of the line.
A transmission line has the following per-unit-length parameters: L = 0.5 H/m, C = 200 pF/m, R = 4.0 /m, and G = 0.02 S/m. Calculate the propagation constant and characteristic impedance of this line at 800 MHz. If the line is 30 cm long
A sinusoidal signal described by Cos (2pit+pi/4) passes through a linear time invariant (LTI) system that applies a gain of 2 and a time delay of 0.125 seconds to the signal. Write the mathematical expression that decribes the signal that will com..
