A Gaussian random process having a mean value of 2 and a variance of 4 is passed through an ideal half-wave rectifier.
a) Let Xp (t) represent the random process at the output of the half-wave rectifier if the positive portions of the input appear in the output. Determine the probability density function of Xp (t) .
b) Let Xn (t) represent the random process at the output of the half-wave rectifier if the negative portions of the input appear in the output. Determine the probability density function of Xn (t) .
c ) Determine the probability density function of Xp (t) Xn (t) .
The nickel- cadmium (nicad) battery is a secondary battery, meaning it can be recharged. it has the following reactions occuring during discharge: A nicad battery has .87 g of cadmium, which is the limiting reactant.
In order to eliminate the cost of calling cards, the company in the above problem is considering a new policy that requires blocked callers to redial over and over until they get a trunk.
Twenty voice signals are to be multiplexed and transmitted over twisted pair. What is the bandwidth required (in bps) if synchronous time division multiplexing is used
Design a PD Controller G_c(s) = K_p + K_d*s using the root-locus method such that the closed-loop system has a damping ratio, zeta = 0.7 and a natural frequency, omega_n = 0.5 rad/sec.
Why then do we even use JFETs as amplifiers What is it that make them attractive even though they are non-linear? How do we minimize the effect of their non-linearity
explain the function of frequency dial and frequency range.
Suppose a data array has 30 numbers sorted from low to high already, where no two numbers are equal. We need to search whether any of the two randomly given key numbers, key1 and key2 is in the array. If yes, then find out the position index(es) f..
Consider the interval [0,30]: y[n+2] - 0.6y[n+1] - 0.16y[n] = 5x[n+2]. a.) Find zero-state response if the input is x[n]= 4^(-n)u[n] b.) Find zero-state response if the input is x[n]= cos(2npi/6)u[n]
The voltage across a 0.2 H coil is given. What is the sinusoidal expression for the current?
The voltage across a resistor is given by Ohm's Law: V=R I. Write a program that asks for resistance R in ohms, and current I in amps for several resistors, then calculates and displays the voltage across each resistor.
the output voltage of battery drop from 6V .With no load to 5.2V with a load current of 400mA. calculate the internal resistance.
Assume the initial state is steady (y = 0 at t = -0) a) Determine the transfer function of this process in the s domain. b) If the input is a ramp change in u(t) = 4t, determine the value of y(t) when t = 10s.
