An audio signal s(t)generated by a loud speaker is reflected at two different walls with reflection coefficients r1 and r2. the signal x(t) recorded by amicrophone close to the loud speaker, after sampling is;
x(n)=s(n)+r1*s(n-k1)+r2*s(n-k2)where k1 and k2 are the delays of the two echoes.
a) determine the autocorrelation rxx(l) of the signal
x(n)
b) what happens if r2=0?
c) can we obtain r1,r2,k1, and k2 by observing rxx(l)?
Frequency Range, Local Oscillator Frequency, Image Frequency, and Attenuation, A radio receiver for the AM broadcast band covers the frequency range 550 to 1600 kHz. The IF frequency is 455 kHz and the local oscillator is above the received signal..
Ziegler-Nichols Open Loop Tuning Often, when working with a faster loop, many people will opt only for a PI control philosophy
Compute the inverse Fourier transform for X(ω) = cos 4ω. 5. A signal with the highest frequency component at 10 kHz is to be sampled. To reconstruct the signal, the sampling must be done at a minimum frequency of?
Can you confirm-The outputs of two"NAND" gates are connected to the inputs of an "EXCLUSIVE OR" gate.Each of the "NAND" gates has one input at logic high level and the other input
Modulating Radio Frequency Carriers to Carry Digital Data, Digital radio transmission requires the use of a carrier wave which is modulated by the digital data.
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 1 kHz sine wave signal with a power level -10 dBm is applied to the input of the amplifier. What is the power at the amplifier output in dBW?
How a transformer works and apply those rules to a transformer where the primary core cross-sectional area is twice.
General questions for network communications, A user message is split into 15 frames, each of which has an 80% chance of arriving error-free. If no error control is used by the data link layer, how many times must the message be sent on the averag..
In order to eliminate the cost of calling cards, the company in the above problem is considering a new policy that requires blocked callers to redial over and over until they get a trunk.
In this project we will consider the control of a synchronous generator supplying electricity to the grid.
A sinusoidal voltage with a peak-to-peak value of 15 v is applied to an RC high-pass filter. If the reactance at the input frquency is zero
