1) Determine the transfer of second-order highpass filter with a cutoff frequency of 900 Hz and passband gain of 1 using a butterworth type.
2) Design a filter for your transfer function from question #1 using the sallen-Key topology.Find all the values of the circuit elemnts and draw the circuit.
3) Given an analog signal
x(t) = 5 cos(6500pi t)+2 cos(8000pi t) +3 cos (12000pi t), for t>=0
sampled at a rate of 9000 Hz
a) Plot the spectrums for the range from 0 Hz to 25000 Hz. Make sure to label the frequncies.
b) sketch the recoverd analog signal spectrum if an ideal lowpass filter with a cutoff frequncey of 4.5 kHzis used to filter the sampled signal.
c) Determine which frequency (ies) will be the aliased one(s). Explain
An Ideal Low Pass Filter: The impulse response of an ideal low-pass filter is h(t) = sin(t)/t (or the sinc signal). (a) Given that the impulse response is the response of the system to an input x(t) = f(t)with zero initial conditions
Consider a discrete-time linear time-invariant system with impulse response h[n]. If the input x[n] is a periodic sequence with period N (i.e., if x[n]=x[n+N]), show that the output y[n] is also periodic sequence with period N.
write a program that would send out through the serial port an array of twenty bytes of data( need a FOR loop) stored in memory locations starting from 30H( must use a ponter) with even parity added as the ninth bit.( skip baud rate).
Needs to oscillate 5 times per second. Amplitude envelope increases 25% every second. Amplitude is 1 at t =0. The derivative at t = 0 is 54.6371. the sinusoid has to be a cos(2*pi*5*t) for the exponential exp(at).
Find the final yield for a nine-mask-level process in which the average fatal defect density per cm2 is 0.1 for four levels, 0.25 for four levels, and 1.0 for one level. The chip area is 50 mm2.
A rectangular chip has a top surface of 0.5 cm by 2 cm cooled by air at 20 oC with h = 150 W/m2.K. There are also 16 connector pins, 1 mm wide, 0.5 mm thick, 6 mm long and k = 60 W/m.K attached to a circuit board at 30 oC.
The power amplifier for a car stereo amplifier has a rated output power of 750 watts when operating at room temperature. Assuming a Class B amplifier with the maximum theoretical efficiency is used,
Construct the adder for 2 digit decimal numbers presented in BCD code. 4 bit binary adders and additional logical gates. The BCD adder for each decimal digit can be implemented with two 4 bit binary adders where the second adder.
