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.
A wave is a disturbance which transmits power and momentum from one place to the other without the transport of matter.
The displacement of body in particular second is given by the equation Sn=u+a (2n-1)÷2, u is speed and a is acceleration. Dimensions of Sn are?
A single-phase transformer has a voltage ratio of 6:1 and the h.v.winding is supplied at 540V. The secondary winding gives a full load current of 30A at a power factor of 0.8 l
