In Example 3.1 we determined the minimum value of m (t) using MATLAB. Write a MATLAB program that provides a complete solution for Example 3.1. Use the FFT for finding the amplitude and phase spectra of the transmitted signal xc(t).
Example 3.1
In this example we determine the efficiency and the output spectrum for an AM modulator operating with a modulation index of 0.5. The carrier power is 50 W, and the message signal is
Assume that the "expert" really knows nothing about wine and randomly assigns ranks to the three wines. One of the wines is of much better quality than the others. What is the probability that the expert ranks the best wine no orse than second be..
the plates of a parallel plates capacitor are 5mm apart and2m2 in areathe plates are in a vacum.a potential
A 10-hp, 230 V, 60 Hz, three phase Y- connected, synchronous motor delivers full load at a power factor of 0.707 leading. The synchronous reactance of the motor is j5 Ω per phase. The rotationnal loss is 230W and the field winding loss is 70W.
An 8-bit DAC outputs a value of 9.961 V when the input is FF (hexadecimal). What is the output when the input is 5A (hexadecimal)
many hoped an investment by the current administration in clean energy would improve our electric grids and create
If the voltage drops by 20 % , what will be the current, assuming nothing else changes If the resistance of the device were reduced by 20 % , what current would be drawn at 240 V
Typically, a speech signal that can be understood over a telephone shows frequencies from about 100 Hz to about 5 KHz. What would be the sampling frequency fs (samples/sec) that would be used to sample speech without aliasing.
For a certain source-free parallel RLC circuit, R=1k-ohm, C=3uF and L is such that the circuit response is overdamped. Write an equation for the voltage across the resistor if it is known that v(0-) = 9V and dv/dt|t=0+= 2 V/s
What is mutual coupling in a magnetic circuit? and What is coefficient of magnetic coupling ? Need the ansswer for this Question with full explanation .
If the machine is totally off the line, then both sensor inputs will be off. Implement the controller using a finite state machine. Choose a Moore or Mealy format as appropriate.
Derive and graph the electric field based on V-bi( built in Potential). Derive the depletion width (w) from built in potential and equilibrium charge equation. graph Depletion width and E-feild in forward bias.
