1) Calculate w in radians per second for each of the following:
a. f = 30 Hz
b. Period = 20 ms
2) Determine the rms values for each of the following:
a. v = 100 sin wt V
b. i = 8 sin 377t A
Design an RC-Low Pass Filter with cutoff frequency at fc=0.5GHz and plot its frequency response and design a parallel resonance circuit with resonance frequency of 30kHz and bandwidth of 20kHz and plot its frequency response.
A random variable X has a variance of 9 and a statistically independent random variable Y has a variance of 25. Their sum is another random variable Z=X+Y. Without assuming that either random variable has a zero mean
2. What is the expected output frequency of a sample and hold system if fs= finput 3. Which is input frequencies will give an output frequency of 50 Hz when put through a sample and hold system if our sampling frequency is 488 Hz
A 3 phase 50hz star connected motor has rotor resistance and stand still reactance of 0.025ohm and 0.35 ohm respectively. The full load slip is 5% calculate the resistance per phase of a star connected rheostat
A) What is the rms current in the circuit B) The primary side of the transformer has 20 times as many turns as the secondary side. What is the rms voltage across the primary side of the transformers
What is the PIV required of the diode? A half-wave rectifier employing a 12-V-rms 60-Hz sine-wave source and no dc load is filtered using a polarized electrolytic capacitor having a small leakage current.
A three-phase steam-turbine synchronous generator is connected to an infinite bus. The generator excitation current is IF=1000 A at the time of synchronization with the bus. The generator has a synchronous reactance of Xs =1.5 per unit.
First draw the transmit con-stellation and the receive constellation with ideal phase tracking and sampling. Note:they are obviously the same constellations. Now, assume that receiver synchronization is off by a phase angle.
1. Write an algorithm to carry out subtraction of two binary numbers (the skeleton was given in the class). Include all the conditions for the given numbers. 2. Write an algorithm to carry out multiplication of two binary numbers using r..
A chopper is used to control the power flow from a dc source voltage of 125-V to a battery whose voltage is 240-V. The power transferred is 60 kW. Determine the duty cycle and the average input current.
A number stored in IEEE single precision floating point format has S=0, E=0111 1101, and F=0.1000 0000 0000 0000 0000 000. What is this number in decimal
