An FM modulator has output
a. Sketch the phase deviation in radians.
b. Sketch the frequency deviation in hertz.
c. Determine the peak frequency deviation in hertz.
d. Determine the peak phase deviation in radians.
e. Determine the power at the modulator output
An Emitter follower with a BJT biased at Ic = 1mA and having β = 100 is connected between a source with Rsig = 20kg and a load RL = 1kg. a) find Rin, vb/vsig, and v0/vsig. b) If the signal amplitude across the base-emitter junction is to be limitd t..
Draw a Nyquist plot of G(s) and examine the stability of the closed-loop system.
The receiver takes the three received bits and decides which bit was sent by taking the majority vote of the three bits. Find the probability that the receiver makes a decoding error.
What is the bandwidth over which you need to equalize the channel and determine the delay of the delay elements.
Determine the magnetic field B at the point P (You do not need to derive any formulae that you use for fields due to current elements with standard shapes).
To put this number into perspective, on June 20, 2002 the US national debt was $6.1e12, which is about $21,000 for each of the 288 million US citizens. What number when multiplied by the US national debt equals the cost to toast the bread.
ASSIGNMENT: Sustainability analysis of a design and sustainable manufacturing routes for critical parts
The carrier wave of frequency 100 MHz is frequency modulated by a sinusoidal wave of amplitude 20 V and frequency 100 kHz. The frequency sensitivity kf = 25 kHz/V. 1. Write expression for FM modulated wave s(t) if Ac = 1 V.
b)If the calculator produces three digit random numbers that are uniformly distributed between 0.000 and 0.999, find the variance of the sample mean. c) How large should the sample size be in order to obtain a sample mean whose standard deviation i..
An 80 kHz sinusoidal voltage has zero phase angle and a maximum amplitude of 25 mV. When this voltage is applied across the terminals of a capacitor, the resulting steady state - state current has a maximum amplitude of 628.32 microamps.
A signal x(t)=sinc(200*pi*t) is sampled (multiplied) by a periodic pulse train. Find and sketch the spectrum of the sampled signal. Explain whether you will be able to reconstruct x(t) from these samples.
Historically op amps and comparators have a lot of similarity in their internal circuit designs. However, they have very different uses in application circuits. Let's talk about these differences.
