For a low pass Butterworth filter, given a prewarped stop band edge frequency of 24621.468 radians/second and a prewarped pass band edge frequency of 2599.358 radians/second, if the gain at the edge of the stop band is -40 dB, calculate the filter order, n, required to meet these specifications.
Design the counter using D-flip-flops such that the state codes are the output values of the circuit. For example, when the circuit is in state 011, the output LED's display "off" "on" "on". Thus, no output equations need to be designed.
A controlled three-phase six-pulse AC/DC converter is supplied with 60 Hz voltage of the line-to-ground RMS value U = 240 V with the output current ideally filtered by an inductor. The maximum DC power of the converter (Pd)max = 50 kW.
1. Calculate the sample values for one period. 2. What is the Nyquist sampling rate for this waveform 3. If the samples are converted to 8 bits, find bits for each sample values. 4. What is the quantization step value and quantization error
Electrons are moving from left to right through a conductor at the rate of twelve billion per second. a. A current variable I1 is defined with reference direction from left to right in this same conductor. What is the value of I1? Use proper SI un..
Message signal m(t) = 0.6sin(27r3000t + pi/9) For a carrier signal with amplitude Ac = 4,fc = 40MHz, What is the signal bandwidth if we use AM with ka = 0.7 DSB-SC FM with kf = 5000 - HZ/V
design a circuit using an inverting amplifier that will produce a +- 10-V output signal corresponding to the bed position and deliver it to a 1k load. The output should be 0V at when the bed is in the center position
An electrical energy source forces a constant current of 500(mA) through a light bulb for one hour. If 12.6(kJ) is given off in the form of light and heat energy, calculate the voltage drop across the bulb.Use Engineering Notation with 3 decimal p..
There is a circuit with a 12V DC battery, 500mH inductor, a 45 ohm resistor, and a switch all in series. Suppose the switch has been closed for a very long time. What is the magnitude of the current through the inductor. Is it constant, increas..
A torque of 10 N.m is applied to a uniform disk shaped flywheel. The flywheel has a mass of 20kg and a radius of 0.5m. At t=0, the flywheel is at rest. How much energy is stored in the flywheel at the end of 20 sec
A voltage of 60cos(4πt) V appears across the terminals of a 3mF capacitor. Calculate the current through the capacitor and the energy stored in it from t=0 to t=0.125 seconds.
Five periods of the signal s(t)=sin(2500pi*t) are sampled at a sampling frequency of 4000 Hz. a. Does this sampling frequency meet the Nyquist requirement for the signal? b. How many samples are collected
(a) Write down a differential equation modeling the current I(t) (b) Assume that V=0 and I(0)=Io. Find the solution to the differential equation in part a. (c) Assume that V>0 is a constant and I(0)=0. This corresponds to adding a switch to the circu..
