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.
The graph below shows a sequence of alpha and beta decays, labeled 1, 2, 3, and 4. Consult Table 30-1 as required. a) Which shows alpha decays, and which represen
What are the basic reasons for loss of residual magnetism? How do you get it? What is the requireable and maximum DC voltage is to be applied to get back the residual magnetism?
The charged particles whose flow in a exact direction constitutes the electric current are known as current carriers. In separate positions current carriers are dissimilar. (i)
