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 molecular theory of magnetism was given by Weber and modified later by Ewing. According to that theory - Each molecule of a substance is a complete magnet in itself. Though,
The SI unit of pressure is the: a) Torr b) Dyne per centimeter squared c) Atmosphere d) Pascal Ans: The SI unit of pressure is the Pascal.
parsec: The unit of distance explained as the distance mentioned by an Earth-orbit parallax of 1 arc sec. It equals approximate 206 264 au, or about 3.086 x 10 16 m.
