A standard test for the operation of an FM system is to examine the output spectrum when modulated by a standard test tone. You're examining an FM broadcast tx modded by a 1kHz tone. Level of the tone is set to ensure that the 100Mhz carrier is deviated to a peak deviation of +/-75kHz.What's the min BW containing 99% of power? (Do not use Carson's Rule, find amplitude of each sideband and sum).What is occupied BW if modulating signal is now 7.5kHz?Now compare to Carson's Rule Approximation.
Mike and Susan hope to retire a few years early, they decided to pay closer attention to the predicted amount of retirement benefits and do some analyses on the numbers. They found that their projected benefits are substantially the same.
Given an ideal op amp to implement designs for the following closed-loop gains, what values of resistors (R1,R2) should be used. Where possible, use at least one 10-kohm resistor as the smallest resistor in your design.
a. Express the transfer function in descending powers of s with the coefficients of the highest power of s unity in both the numerator and denominator. b. Determine where the poles and zeroes of the transfer function are located.
What are the respective advantages and disadvantages of the asynchronous and synchronous communication modes from a reliability perspective?
For each of the following waveforms, determine its period, frequncy, and effective value a) 5 V b) 2sin80t-7cos20t+5 V c) 5cos50t+3sin50t V d) 8cos^290t mA
Develop a system to help students learn Morse Code. The system will have one input and 26 outputs (one per letter). The user sends in Morse Code pulses on the input, and as characters are completed the appropriate letter is lit up momentarily.
Design a second-order band-pass IIR filter with center frequency of 200 Hz when the sampling frequency is 1000 Hz. In order to ensure the filter stability set the poles at 0.94 radial distant from the origin
Heat is added until the final volume is twice the initial volume. Assume that Helium behaves as an ideal gas. Use the table provided to determine the specific heats of helium and determine the following. Find the temperature at the final state.
A mass memory system has 24 address lines and 16 data lines. (a) What is the size of this memory system (b) How many 64K x 8 memory chips are needed to build this memory system
Find out the voltage that must be applied to the high voltage winding in order to provide rated voltage at the load under full-load conditions at 0.80 lagging power factor.
A 480-V, 60Hz, 500-hp 0.85-PF-leading eight-pole delta-connected synchronous motor has a synchronous reactance of 0.6 ohms and neglible armature resistance. Ignore its friction, windage and core losses for the purposes of this problem.
An electric flux density is given by D = D0 a, where D0 is a given constant. (a) What charge density generates this field (b) For the specified field, what total charge is contained within a cylinder of radius a and height b
