A modulating signal consists of two sinusoidal components: 1 kHz and 3 kHz. The transmitter carrier frequency is 80 kHz. If the signal is applied to an ideal DSB transmitter, indicate the output frequencies (in kHz).
Three delta connected transformers are supplying a balanced reactive load. The primary line voltage is 480 volts and the primary line current is 20.5 amps. The load power used is 4.8kw. What is the power factor, the apparent power supplied
a) Find and plot the straight-line approximations to the amplitude and phase response bode plots b) sketch the approximate amplitude-response bode plot od this system using the straight-line approximation and approximate amplitude values at the br..
A 10 K-ohm pot is used as a position sensor with a 10 -V supply. The input resistance to the interface circuit is 50 K-ohm. Find the loading error when the pot is in the middle of its range.
a. What are the cyclic frequency (in Hz) and period of this signal b. Express this signal in the Quadrature and Sine/Angle forms. c. Express this signal in terms of complex exponentials (hint - use Euler's identity equation).
Working with wired rifle microphones and radio microphones, The theatre's concerns when changing of wired rifle microphones to a radio microphone system are
Design a common collector circuit using a npn silicon transistor having Beta=90 with Vcc=20 V The desired Q-point is Vce=14V and Ie=2mA
You must design a three axis position indicator for the latest robot arm. Using no more than two operational amplifiers, design a circuit that uses three inputs, v1, v2, and v3 to produce an output signal vo=3 v1-2 v2-5 v3.
air expands through a nozzle at a rate of 1kg/sec. the outlet is at 15kpa and the inlet is at 400kpa,150degree and 35m/sec. assuming the process to be reversible and adiabatic, what is the exit velocity.
An angle-modulated signal with carrier frequency ???ωc=2πx106 is described by the equation φEM(t) =10cos(ωct +0.1sin200πt) (a) find the power of the modulated signal. (b) find the frequency deviation Δf. (c) find the phase deviation ΔΦ.
sketch the spectrum
Design a circuit with input p and output f that will output f = 1 if the past three inputs (not including the current input), formed either 010 or 000. Otherwise, f = 0. Note: This is a Moore-type finite-state machine.
For a discrete-time LTI system, the imput signal is x[n], impulse response is h[n] and output is y[n]. Analytically determine the output y[n] in each of the above cases. x[n]=anu[n-2],|a|
