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
There are two charge distributions: one in a infinite plane of charge in x=-2 with a surface charge density of 3mC/m2, abd a infinite line of charge with a linear charge density of -3mC/m that goes through the points A(0, 0, 3m) and B(0, 3m, 0).
if the analog signal to be quatized is a sinusoidal wave form x(t)=9.5sin(2000*pi*t), and if the bipolar quatizere uses 6 bits - what are the number of quantization levels - quantization step size or resolution, delta, assuming the signal range
A current amplifier with R=9 kohm Ro=1 kohm and Ais=100 is connected between a 8 V voltage source with a source resistance of Rs=1 Kohm and a load resistance of RL=9 Kohm.
Wien Bridge Oscillator: Simulate the oscillator in Simulink with a gain block of 3.1 and a feedback transfer function of s/(1 + 3s + s2). Include a saturation element and limit the amplitude at 10v peak to peak.

A total charge of Q is uniformly distributed on the inner wall of a spherical dielectric shell having inner and outer radius of a and b. The relative dielectric constant of the shell is fr.
The voltage of a resistor is calculate by the Ohm`s Law: V = R I. write a program that will input resistance R, current I for several resistors, and will calculate and display the voltage for each resistor.
discharge a capacitor of 1mF charged with a voltage of 1 volt we connect it, at time t = 0, with a esistor of R ohm. When we measure the voltage we find it to be V(r) (t) = e ^(-t) u(t). Determine the resistance of R. If the capacitor has a capaci..
Assessment on Electricity and Circuit Theory, What part of a cable are insulators and conductors? Describe, in terms of charged particles, why some objects are electrically attracted to each other, while others repel each other?
