The sampling frequency in a DSP system is fs=8 kHz. Anti-aliasing filter used in the system is the second-order Butterworth filter with cutoff frequency of fc=3.4 kHz. What is the percentage of aliasing level at the frequency f=2.5 kHz?
Write a program that uses the rand_float functions developed to generating sequences of random floating-point values between 4 and 10. Then compare the computed mean and variance to the theoretical values computed.
a bar of n-type germanium and we place an E field going to the right across it and create a pulse of excess minority carriers (holes) in the center of the bar at time t=0. In other words we are performing the Haynes Shockley Experiment on the bar
A bar magnet is cut into 2 parts ,one part is kept over the other so that the pole c2 is above c1. IF M is magnetic momentof the magnet. What will be magnetic moment of the combination
The voltage and current at the terminals of an ideal element are 0, for t _ (minus equal) 0s. V(t) = 100(1-e^(-300t) V, i(t) = 15e^(-400t) mA. Find the maximun power absorbed by the element by the element at t = 10ms
a. Functionally, how do closed-loop systems differ from open-loop system b. State one condition under which the error signal of a feedback control system would not be the difference between the input and the output.
A balanced Δ connected load of 15 + j9 Ω/phase is being fed by a Δ connected source. Each of the three lines feeding the load from the source has 0.5 + j0.3 Ω impedance. The voltage at the source is 400 VLL.
with general block diagrams, show how to obtain the following frequencies from a 10 MHz clock by using single flip-flop, modulus-5 counters, and decade counters for 5MHz 2.5MHZ 2MHz 1MHz 500kHz 250 kHz 62.5 kHz 40 kHz 10 kHz 1 kHz
Suppose 200 gpm of water is taken from a creek and delivered through 800 ft of 3-inch diameter PVC pipe to a turbine100 ft lower than the source. If the turbine/generator has an efficiency of 40%, find the electrical power that would be delivered.
Next find a 95% confidence interval for the proportion theta of defective chips and also find a one sided 95% confidence interval for the proportion of defective ones. Refering to this problem, how large a ssample should be taken
You are given a black box, a 6 k Ohm resistor, a 40 nF capacitor, a voltmeter, and an ammeter. With these supplies you complete the following measurements at 950 Hz: You place the resistor and capacitor in series and measure a current flowing.
For a photovoltaic installation at latitude 30°N, you have the option to position the panels facing south at slope angles of 0°, 10°, 30°, or 90° to the horizontal plane. Determine the panel orientation you would choose to obtain maximum energy
An electric field of 3.10×105 is desired between two parallel plates, each of area 36.0 and separated by 0.620 of air.What charge must be on each plate?
