Compute the complex conjugate of each of the follwoing expressions: (a) -1; (b) -j/5 < 20 degrees (c) 5e^(-j5) + 2e^(j3); (d) (2+j) (8<30 degrees)e^(-5t)
write a script that will call: a function to prompt the user for an angle in degrees and call a function to calculate and return the angle in radians (note:pi radian =180) and call a function to print the result.
Maximum value of frequency deviation is fixed at 75 kHz for commercial broadcasting by radio. Modulation frequency W = 15 kHz, then find the transmission bandwidth of signal and deviation ratio.
A voltage divder is required to produce a 5.5V output from 12V source. If one of the resistor values is 1.0k, what value is required for the second resistor so that the voltage across the 1.0k resistor is 5.5V
An MFSK modulation scheme with M = 4has a carrier frequency of 250 kHz, a difference frequency of 25 kHz, and two bits per signal element. Make a frequency assignment for each of the possible data combinations.
The tuning capacitor of a Wien bridge oscillator is 100 pF and the frequency is 5 kHz. To what value of capacitance pF should the capacitor be changed to if the frequency is to be changed to 2 kHz
Calculate the energy stored by a 1 μF capacitor with 200V applied across its terminals. Determine the magnitude of net charge stored on each plate and the total net charge on both plates.
The power supplied by a certain source is a constant 7.5 W over the first 5.8 min, zero for the next 2.8 min, a value that increases linearly from zero to 10 W during the next 8.8 min, and a value that decreases linearly from 10 W to zero
design an IIR high-pass filter using bilinear method in a system with sampling frequency of 100 Hz. The lower and higher cutoff frequencies are at 18 Hz and 35 Hz respectively. Pre-warp the cutoff frequencies.
Bode plots were introduced in my second circuit analysis class, but I really didn't think it was important because it looked like an outdated tool no longer in use.
What is the clearance requirement for a 120/240 V, single-phase, three-wire service at the point of attachment to the building Over the driveway Over the main roadway
Saw on internet some equations to convert from frequency in hertz to mph. Some equations need a gear ratio while others do not. I found the equation mph = circumference * RPM * 60.
A 150 MVA, 24 kV, 123% three-phase synchronous generator supplies a large network. The network voltage is 27 kV. The generator operates with an induced voltage, which is twice the rated line-to-neutral voltage.
