In a RC circuit with input Vi(ω) and output Vo(ω)
1. Calculate Vo( ω)/Vi(ω) for R=5KOhm. What is the frequency when Vo(ω)/Vi(ω) =-3 dB and what is the frequency when Vo(ω)/Vi(ω) = -20 dB?a. 6.64 KHz and 66.4 KHzb. 9.95 KHz and 99.5 KHzc. 19.9 KHz and 199 KHzd. None of the above; see Problem Work
2. The output response for a system is given as Vo(t) = A(1-e^-at)sin(ωt). Is this a proper representation for an output response given that it contains a sinusoidal term? Fully explain your answer.
The surface of the sun has a temperature of 6000 K. Calculate the wavelength at which the sun emits its peak radiancy.
An LVDT is used in an accelerometer to measure seismic-mass displacement. The LVDT and signal-conditioning output is 0.31mV/mm with +/-2cm maximum core displacement.
Problems for the basic concepts of Induction motor(IM) taking care of slip and syncronous speed and motor speed and its relationship, A 50 Hz induction motor operates in such a way that the slip is 1.45.
Consider a signal x(t) = 10 cos(2pi*fct + 4 cos 2pi*fmt). Assume frequency modulation. The message frequency fm = 2:3 kHz. Calculate the modulation index and find the bandwidth when.
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?
Give three advantages of a three-phase system over a single-phase system There are two basic three-phase connections, the wye connection and the delta connection. Draw a labelled diagram showing the wye connection
Rate at which succesful packets arrive at network node, After traversing a wireless filled channel packets arrive at a networks node according to a Poisson process with rate Lambda
The river estuary is tidal causing the surface level of the water to rise and fall. At certain times of day, reflections from the water surface cause deep fading of the received signal.
A 35-year old female worker receives an x-ray exposure of 5.2 rad (whole-body) while carrying out emergency procedures in a nuclear accident. Discuss the health risks assumed by this worker as a result of the radiation exposure.
For the given circuit, determine the function of it I.e. is it OR gate? Or AND gate,.. Show all your answer, also draw the symbol and truth table of it.
Magnitude bode plot for any given transfer function Can some one teach me an easy way to make a bode plot for any given transfer function magnitude only (not phase).
Three two-input "AND" gates have their outputs connected to an "OR" gate. The first "AND" gate has each of its inputs at logic HIGH level. The second "AND" gate has each of it's inputs at logic LOW level.
