A bandpass filter with a center frequency of 6kHz, a 3dB banwidth of 1 kHz, and a 50 dB bandwidth of 2kHz is connected to a signal generator that outputs a one volt square wave at a frequency of 2kHz. A spectrum analyzer is connected to the filter output. What frequencies would you expect to see on the spectrum analyzer? Please be thorough about the answer, I have not taken a signals class in quite some time and always had truble understanding this conceptually and mathematically.
A vibration trandsucer measures a sinusoidal signal with up to a 100-hz frequency and an amplitude of + and - 5 v. Superimposed on this signal is an additional signal with a freq of 1000 hz. and amplitude of .2
A certain load takes 10kW at 0.5pf lagging when connected to a 230V, 60Hz source. The supply company charges a penalty when the power factor fall below 0.8. What size of capacitor must be used in order to avoid penalty
What is the peak frequency deviation of the FM signal and bandwidth of the FM signal? The signal is received with CNR = 30.0 dB. What is the SNR of the recovered video signal at the radio receiver output?
Half and Full Wave rectifying and Fourier Rectifying a sinusoidal provides a way to create a dc source. In this problem we consider the Fourier series of the full wave and half wave rectified signals. The full wave rectified signal xf(t) has a per..
For a 128-PSK modulator with an input data rate equal to 56 Mbps and a carrier frequency of 100 MHz, determine (a) minimum required bandwidth and (b) baud rate.
With the 1s complement scheme, how does the receiver detect errors? Is it possible that a one bit error will go undetected? How about a two bit error?
Assume that we try to predict this sequence with a BHT using one-bit counters. The counters in the BHT are initialized to the N state. Which of the branches in this sequence would be mis-predicted?
Explain how primitive values like doubles are passed between functions in Java. How are string objects passed between functions in Java How are static methods different from non-static methods How do you invoke a static method
Consider a zero-phase sine function, x(t), with frequency ?=1.3rad/sec. What is the minimum positive time shift needed to turn this function into a zero-phase cosine of the same frequency
Discuss why phasor analysis can only be performed on single-frequency circuits. For multiple frequencies what type of analysis must be performed Discuss the advantages of transforming time-domain circuits into the corresponding frequency domain.
An induction motor absorbs an apparent power of 500 kVA at a power factor of 75%, calculate the active and reactive power absorbed by the motor, what purpose does the reactive power serve
