Question about AC CircuitsA voltage amplifier ideally should have the input-output relationship of vo= 100*vi but in practice the relationship is vo = vi*(98 + (2/k)*vi), where k= 1*10^–3V.
(a)Determine the expression for the output voltage when a 10 mV(peak), 800 Hz, sinusoidal input signal is applied to the amplifier.
(b)Sketch the frequency spectrum of the output voltage.
(c)Sketch the waveforms of the harmonic components in the output and the resultant output voltage.
(d)Calculate the percentage second harmonic distortion present in the output.
(e)Calculate the percentage error in the output voltage compared to its ideal value at the instant of time when t= 1/3200 seconds.
If we have a 600ohm transmission line terminated with a 1200ohm resistor, how long must the transmission line be if the input impedance is purely real?
What is the maximum message bandwith for which the system operates satisfactorily? Determine the output signal to quantizing noise ratio when a full-load sinusoidal modulating wave of frequency 1 MHz is applied to the input.
Tones Input In To An Amplifier, Suppose two tones are input in to an amplifier. The tones are pure sinusoids with one at frequencies 8GHz and the other at frequency 8.03GHz,(delta f =0.03GHz).
In a typical mobile communications base station (or cell site), a radio frequency (RF) signal is amplified in the base station and then sent (over cable) to the antennas at the top of the tower.
A certain cache has an access time of 2 nanoseconds and a hit percentage of 95%. If the main memory access time is 8 nanoseconds, what is the average access time for a read operation?
Determine ideal impulse response using inverse discrete-time Fourier transform. An ideal low-pass filter is described in the frequency-domain by
You are required to determine that this next generation transmission system will require a spectral efficiency of 5 bits/sec per Hertz.
Create a flowchart and pseudo-code for generating a report that prints all of the movies, with all movies made by the same director on one page, as well as the number of movies by each director.
Digitizing an Audio Signal, PAM, ADC, An audio signal has a bandwidth that extends from 100 Hz to 10 kHz. The signal is sampled to create a PAM signal and then digitized by an analog to digital converter (ADC) that has 8 bits.
Write down the principle of energy conversion and give an example for single and double excited system.
How are the left (L) and right (R) signals obtained separately in the radio receiver to drive the dual channel audio amplifier and speakers?
What is the energy in joules stored in the capacitor below, The capacitor is shown with 10 volts on each side of it (plus on the left of the capacitor, - on the right), and C = 20 microfarads.
