Design a Double Sideband Amplitude Modulation (DSBAM) modulator and demodulator system using the SystemView software. The modulating wave m(t) = Amcos(2?fmt) and the carrier wave c(t) = Accos(2?fct) have the following parameters, respectively:Am = 2V, fm = 200Hz, Ac = 1V, fc = 1kHz.The modulator has an amplitude sensitivity ka = 0.4.i) Write the mathematical expression of the DSBAM signal s(t) and determine the value of the modulation index ?.ii) Sketch the DSBAM waveform to scale and label the maximum and minimum peaks.iii) Draw a SystemView block diagram of your DSBAM modulator and demodulator with all the tokens and their parameters clearly labeled and indicated.
A synchronous motor is drawing 90 amps from 240V, 3 phase line at 0.8 pf leading with field current adjusted to 1.2 amps. The synchronous machine Xd is 1.3 ohms. Find a). The power angle delta
For the discrete signals defined as the following: x[0]=4, x[1]=1, x[3]=-1, x[n]=0 for all other integers n. v[0]=1, v[1]=-2, v[2]=3, v[3]=-4, v[n]=0 for all other integers n. Compute the convolution x[n]*v[n] for n
In each of the three phases in a balanced delta- connected load is composed of a 10mF capacitor in parellel with a series-connected 470 ohm resistor and 4mH inductor combination, assume a phase voltage of 400 V at 50 Hz
Sketch the baseband signals for the two users when user 1 sends the bits 011, and user 2 sends the bits 101. Add the signals for the first bit only, and show that the output of the correlator for user 1 is -4, corresponding to a 0

A glass tube with a cross-sectional area of 9^-2 m^2 contains an ionizd gas. The densities are 10^15 positive ions/m^ and 10^11 free electrons/m^3. Under the influence of an applied voltage, the postive ions are moving.
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.
An engineer intends to study an input signal with frequency components of 5, 6, and 10 kHz. It is desired that all other frequencies be filtered out. A) What kind of filter does this require
