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 energy needed to ionize an atom is known as ionization energy. It is the energy needed to make the electron jump from the present orbit to the infinite orbit.
In a pure semiconductor, concentration of electrons in conduction band is equal to the concentration of holes in valence band. In the process of conduction when an electric field i

Can any heat exist without some source of friction?
A laser beam from 200 watt source is focused on an area of 10 -8 m 2 . Determine the magnitude of the Pointing vector of the area.
It explains that when an object is immersed partly or completely in a liquid, it loses in weight similar to the weight of the liquid displaced by it. Let w1 be weight of an obje
