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.
o meteors of rest-mass 0.1 and 0.2 kg, respectively, collide. If the relative speed before collision is 0.1c and an observer sees them coming with an equal and opposite speed and s
Vector Addition While we become students of physics and approach the job of adding vector quantities, we soon become aware of the fact in which the addition of two vector quant

It is the product of either change in an electric dipole with the distance separating them.
Ampere; A (after A.M. Ampere, 1775-1836) The basic SI unit of electric current, described as the current that, while going through two infinitely-long parallel conductors of ne

Imagine an elctromagnetic wave propagating vacuum with electric field Ex=10 2 sinπ(3x10 6 z - 9x10 14 t) V/m, E y =0, E z = 0. Calculate the speed, frequency, wavelength, initial
Explain Centripetal force?? Sir Isaac Newton suggested that motion in a straight line is most natural, and that deviations from this type of motion are caused by a force pullin
The power distribute to a 15 watt light bulb in normal operation is 15 watts. In normal operation how greatly energy is delivered to such a bulb in an hour? Feedback:
Using cross belts cross the belt on the spool pulleys used in C 1 above and turn one of the pulleys. Note that they now turn in opposite directions.
