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.
Whenever there is a relative speed among a source of sound and the listener, the apparent frequency of sound listen by the listener is dissimilar from the real frequency of sound e

Vectors Representing Forces A force can be represented by a vector (drawn as an arrow). The arrow's length is related to the size of the force and the arrow's direction shows y
Energy gap: 1.4ev at room temperature Its charactistics are very closely related to those of germanium. This is under stable, since Gallium is the third column neighbour and a
Low frequency loop impedance: Low frequency loop impedance testing is a useful method complementary to DC bonding testing. A visual inspection of cable bundle shields, complem

Ques: Point out the direction of the current if any induced to flow in the loop by the changing magnetic field. (Describe is the loop as viewed from above.) Answer:
Can you give me few applications of coupled oscillator concepts?
What is a Newton meter? A unit of energy also called a Joule. When a force of 1 Newton is applied on an object for a distance of 1 meter then 1 Joule of energy is used. It is t
