Generate and plot a sampled sine wave with fs=8kHz, of 4 seconds duration, with frequency ω0 = Π/10 and amplitude A = 1.2. The waveform equation is
x(n) = A sin nω
Explain the role of each of the variables in this equation. What is the true (Hertz) fre- quency generated in this case?
Generate a Gaussian random signal vector, v(n), of the same length. Then generate a noisy signal of the form
y(n) = x(n) + αv(n)
(2) Listen to the resulting signal y(n) for various values of α. You will have to choose the value of α experimentally - try both small and large, and investigate the differences. Plot one of the waveforms, and comment briefly on your results.
An aereplane has velocity 500m/s with respect to air. Wind blows with velocity 20m/s along north. Then in what direction pilot should be heading so as to go along North-east direct
What is the Ohm Law? Ohm discovered that the amount of current was directly proportional to the voltage (more voltage gives more current) and inversely proportional to the resi

Comparing a DC circuit to the flow of water A normal DC circuit has a DC voltage source lighting a light bulb. Also displays are a hydraulic system in that water drives a turbi
CPH has rest mass, so how it explained by relativity? Answer; never can we see CPH at rest condition. CPH moves faster than light.
