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.
Explain displacement x(t) is known as displacement and it denotes the position of a body at time. If the displacement is positive then that body is to the right of the chosen
A VDR is a special type of resistor that changes its resistance with rise in voltage. It has a very high resistance at low voltage (below the trigger voltage) and very low resista

Passing Lane A passing lane or overtaking lane is the lane on a multi-lane highway or motorway closest to the center of the road or the central reservation.
THE MAGNETIC CIRCUIT In an electric circuit, a current is established due to the existence of an electromotive force. In the same way, in a magnetic circuit, a flux is establis
