Design a second-order digital low pass Chebyshev filter with a cutoff frequency of 1.5 kHz and a pass band ripple of 0.5 dB at a sampling frequency of 8,000 Hz. Use MATLAB to plot the magnitude and phase frequency responses.
A line of charge with uniform density of 10 microC/m exists in air along z-axis between z=0 and z=10 cms . Find Electric Field Intensity on p1(0, .1, 0)
the atomic weight of sodium is 23 and the density is 0.97*103 kg/m3. calculate the number of electrons in a cubic meter of sodium.
Let Y1 denote the number of married executives and Y2 denote the number of never-married executives among the three selected for promotion. Assuming that the three are randomly selected from the nine available, find the joint probability function ..
build a cicuit that must be able to operate a 3 amp load of the LED while being able to operate at voltages around 3V or 6V. It must be able to keep the LED on constantly while also being able to pulse the LED.
Consider the voltage Consider the voltage reference circuit in Figure P9.86. Using a Zener diode with a breakdown voltage of 5.6V, design the circuit to produce an output voltage of 12V. Assume the input voltage is 15Vand the Zener diode current i..
Important information about Electrical Networks, Engine consumes 5kw of power and a reactive power of 2kvar at current of (3+j2) Amps.
Suppose we transmitted 5 cos wct for logic one and 15 cos wct for logic zero. Find the maximum signal energy. Design a demodulator and show the detection criterion for the output of the demodulator. Finally, find the bit error-rate.
determine the minimum sampling rate necessary to sample and perfectly reconstruct the signal x(t) = sin(6280t) / (6280t).
Also, if the cursorreaches the end of the screen it should wrap around to the otherside of the screen. If no direction is designated, the cursorshould stay put. Also, the system should show the direction selected on a set of 8 LEDs. When the curso..
A square pulse train (i.e. square wave) with low and high voltage values of VL= 0 and VH= 2.9 volts is applied to a DC voltmeter. The voltage measured by the instrument is 0.2 volts. The same signal is applied to an 99 O resistor.
Determine the power consumed by the two elements, determine the current leaving the source, determine the power factor and specify leading or lagging. Also, determine the size of the capacitor (in kVARs) needed to bring the power factor to 1
What are the distinguishing features of the response in the pass-band? What are the distinguishing features of the response in the stop-band? What is an all pass filter?
