Start with a binary channel with a bit rate of 64000 bits/s and we like to transmit a speech signal with a bandwidth of 4 kHz. Find the sampling rate, the number of quantization levels, and the number digits per sqample to transmit using this channel.
The average power absorbed by the load resistor RL should be PLavg = 20.0W or the closest possible value to 20.0W while using integer number of turns.
(a) If E=Exax andH=Hyay, begin with Maxwell's equations and determine the second order partial differential equation thatEx must satisfy. (b) Show that Ex=E0 cos (ωt-βz) is a solution of that equation for a particular value of β.
Design a first-order digital highpass chebyshev filter (.5-db ripple) with a cutoff frequency of 850 Hz and a sampling frequency of 10 kHz. Determine the transfer function using BLT.
Let h(t)= (1/(R*C))*(e^(1/(R*C)))*u(t) be the impulse of an RC circuit and x(t)= u(t) an input to that circuit. 1. Find X(jω) and H(jω), which are the Fourier transforms of x(t) and h(t). 2. Form the product Y(jω)=H(jω)*X(jω) the Fourier transform of..
A sinusoidal current is zero and increasing at t = -3.33ms; the next zero crossing occurs at t = 6.67ms. a) calculate T, F, and W. b) if i(0) = 25.98 A, Find i(t). c) By what angle does i(t) lead another current i(t) = 5 sin (wt - 5°) A.

Calculate the performance of the motor at a slip of 0.035. (The auxiliary winding is open-circuited.)
At the altitude the airplane flies there is a wind, blowing horizontally from north to south (negative y direction) at a speed of 100 km/h.
Find the sides and angles of the triangle whose vertices are i-2j+2k,2i+j-k and 3i-j+2k.
Suppose the above device is to be used as an 8-way power splitter (let's say only the top-most input is used). Let the input power be P. Assuming a cross-coupling coefficient of f and ignoring excess losses, what are the possible power levels Pi a..
