An FM modulator is followed by an ideal band pass filter having a center frequency of 500 Hz and a bandwidth of 70 Hz. The gain of the filter is 1 in the pass band. The un modulated carrier is given by
a. Determine the peak frequency deviation in hertz.
b. Determine the peak phase deviation in radians.
c. Determine the modulation index.
d. Determine the power at the filter input and the filter output
e. Draw the single-sided spectrum of the signal at the filter input and the filter output. Label the amplitude and frequency of each spectral component.
A firm leases land from you for 15 years to build a warehouse. As payment you will own the building after 15 years estimated to be worth $400k however you must pay taxes and maintenance of $15k per year.
A 4-bit adder will be used to add a 3-bit unsigned number (0-7) and a 2-bit unsigned number (0-3), producing a 4-bit result. Design a combinational circuit with a complete truth table, K-maps and circuit diagrams using multiplexers and discrete lo..
Consider three identical metal spheres that are mounted on insulating stands. Sphere X is neutral, sphere Y has a charge -1q, and sphere Z has a charge +4q. X and Y are touched together and then separated.
The data inputs I0 through I7 are wired as follows: I0 = I1 = 0, I2 = I6 = , I3 = I5 = I7 = 1; and I4 = D. (a) Determine the Boolean function that the MUX implements. (b) Implement the function using a 4×1 MUX with minimum extra logic gates.
Consider a coil wound on an iron core. Suppose that for operation with a given 60-Hz ac current, the hysteresis loop of the core material takes the form of a rectangle, as shown in Figure. The core volume is 1000 cm3. Find the power converted to h..
A total sideband component of 25 volts amplitude is combinedin space with a carrier component of 100 volts. What is the space modulation factor(s) when 30 degrees of misphasing exists be when the two components
Write at least one paragraph explaining why the power factor of the motor changes as the rotor mechanical speed changesin the induction motor. evaluate when the machine is operating in motor mode or generator mode.
An inventor claims to have perfected an engine that wil produce power from energy transferred as heat from a 1000K flame. Energy wil be rejected as heat to the ground at 290 K. A 75 percent energy conversion efficiency is claimed.
The switch of The switch of given Figure is closed at t = 0 s. How long is it until current reaches its steady value. Figure is closed at t = 0 s. How long is it until current reaches its steady value. An unknown circuit containing dc sources and re..
If one of the resistors in a parallel circuit were shorted, what would you expect to see happen and could a shorted component in a parallel circuit cause an open to occur elsewhere.
