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 Tension Force (Ftens) : Force that is transmitted by a string, rope, cable or write when it is pulled tight by forces acting from opposite ends. The tension force is fix
Explain Newton's First Law In 1665, at the age of 23, Newton developed his famous Laws of Motion. They are commonly known as Newton's first, second and third law. Aside from th
Briefly explain with necessary theory how you will calculate refractive index of water/transparent liquid by using Newton's ring apparatus?
