In this computer exercise we investigate the properties of VSB modulation. Develop a computer program (using MATLAB) to generate and plot a VSB signal and the corresponding amplitude spectrum. Using the program, show that VSB can be demodulated using carrier reinsertion.
Design a filter for a biomedical instrument to eliminate DC (f = 0), 500 Hz tone, and its corresponding harmonics. The system sampling rate is 2,000 Hz. Place all the required poles at the origin to obtain a FIR filter.
The donor concentration in a silicon sample at 300K is ND = 1.2 x 1015 cm-3. 1 x 1016 cm-3 acceptor atoms are added to form a compensated p-type semiconductor so that the Fermi level is 0.26 eV above the valence band edge.
Consider an impedance Z = (1 + j) Ohms. The voltage phasor across it is 1 V. What is the apparent power consumed on this impedance. b-) What is the real power consumed on the previous load.
Two infinitely long coaxial cylinders ofradii a and b ( a > b) carry surface charge+ λ and -λ respectively. Find the E field in theregion inside the inner cylinder, between the cylinders, andoutside the cylinders.
the magnetic circuit shown with a mean core length of 52 cm and a cross sectional area of 18 cm^2. the length of the air gap is 0.14 cm. Determine the battery voltage required to obtain a flux density of 1.2 T in the air gap. Use the magnetization..
A ball of radius 1 meter centered at the origin has uniformly distributed over its volume a positive charge Q. a. In moving a positive test charge from the point (x, y, z)= (2, 2, 2) to the point (4, 4, 4), do you have to do work on the test charge..
Design a 4-bit multi-function register that can perform 5 functions: 1) load a parallel number 2)multiply by 4 3)divide by 4 4)divide by 2 5) hold Use the inputs and outputs as described in the symbol shown and assume precedence in the order
Assume that a load Z absorbs power of 150 W at a lagging power factor of 0.8, and the voltage across the load Z is 220 Vms, 50 Hz. What must be the value of capacitor that needs to be connected in parallel with the load Z
A pole currently near frequency f on the z-plane is outside the unit circle.
Why is the "drop out" current less than the "pick up " current in a relay and why is this an important and common feature in a relay
A ray of light in air strikes a glass plate (n=150) at an incidence angle of 50 degrees. Determine the angles of the reflected and refracted rays.
a) Evaluate % overshoot, settling time and peak time if a=4 and b=25 b) Calculate values of a&b so imaginary part of poles remains same but real part increased by 2 times
