Using Computer Example 3.5 as a guide, develop a simulation program for PAM and PPM
Example 3.5
In this example we consider the time-domain waveforms corresponding to VSB modulation and consider demodulation using envelope detection or carrier reinsertion. We assume the same message signal as was assumed Example 3.4. In other words,
Example 3.4
The preceding example demonstrated the required amplitude response of the VSB filter. We now consider the phase response.
Assume that the VSB filter has the following amplitude and phase responses for f > 0:
How do you create a class in Java to enable its object to be persistent What are Java data streams and how are they used to facilitate storage and retrieval of persistent objects
a). Without calculating E(z), find its poles. b). Give the rule that you used in part (a). c). Verify the results of part (a) by calculating E(z). d). Compare the zero of E(z) with that of E(s).
A sample has a T1 of 0.8 seconds. The net magnetization from the sample set equal to zero and then allowed to recover towards its equilibrium value. After 1.0 seconds, what fraction of the equilibrium magnetization value will be present
A circuit that is made from a voltage source in series with the switch then in series with the parallel set of a resistor and a capacitor. The switch is originally open, it is then closed.
a)Write the diffrenece equation for a four-term moving average filter. b) The input x[n] = cos(n pi/6)u[n] is passed through the four-term moving average filter. Solve for the first 5 samples of the output.
As with binary numbers, there are many possiblerepresentations of negative BCD numbers. Signed BCD numbers haveone extra digit position for the sign. Both thesigned-magnitude and 10's-complement representations are popular.
Use a K-Map to simplify the function F(A,B,C,D) = Σ(0,1,2,3,8,9,10,11). Design a circuit that implements this function. Write the VHDL code.
The end of the plates is 30 cm from the tube screen. The kinetic energy of the electrons is 2.80 keV. If a potential difference of 25.0 V is applied across the deflection plates, by how much will the point where the beam of electrons strikes the s..
Suppose you are the supplier and can produce 20 units now but cannot start production on the second 20 units for two months. What price would you try to negotiate for the last 20 units?
Calculate the capacitive reactance/ph such that the load power factor is increased to 0.98 lag and calculate the percentage reduction in line current with this value of capacitive reactance in circuit.
A three phase synchronous motor has the synchronous reactance of 2.1 Ohm and draws 250 A with a lagging power factor for an excitation voltage of 1327 -15 degree per phase. Find the terminal voltage of the motor and power factor of the motor.
Describe how you would use the combination of a short pass filter, a long pass filter, an amplifier and a mechanicalchopper to amplify a 5 mV signal to a 50 mV signal and remove noisefrom the original 5 mV signal.
