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.
Five volts are applied across the plates of a parallel plate capacitor. The distance of separation of the plates is .02 meters. What is the magnitude of the electric field i
Step to improve Power Factor By using static capacitor: Static capacitor is usually used to better the power factor of the power system. As the capacitor draws leading curre
Thevenin's Theorem can be stated as follows: Any two terminal network having a number of e.m.f. sources and resistances can be changed by equivalent simple series circuit of singl
lsolectric precipitation: At isoelectric pH you already know, a protein does not have any net charge. So, they easily aggregate and precipitate without denaturation becaus
12 joule of work has to be completed against an existing electric field to take a charge of 0.01 C from A and B. How much is the potential difference VB-VA.
Commutator: The commutator is a form of rotating switch placed among the armature and external circuit and so arranged that it will reverse the link with the external circuit a
Davisson-Germer experiment (C.J. Davisson, L.H. Germer; 1927) An experiment which conclusively confirmed the wave nature of electrons; diffraction patterns were observed throu
Q Define: Drift velocity. Drift velocity is described as the velocity with which free electrons get drifted towards the positive terminal, when an electric field is applied.
How to convert from only a displacement vs time graph given, to velocity AND acceleration vs time graphs?
A body moving in the positive x direction passes the origin at time t=0. Between t=0 and t=1 second, the body has a constant speed of 24 meters per second. At t=1 second, the body
