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.
There is a maximum depth at which a diver can breathe through snorkel tube because as the depth increases, so does the pressure difference, tending to collapse the diver's lungs. S
Q. Can you define Solar Constant? The luminosity of the Sun L is 3.827×10 26 Watts. When the Sun is straight overhead on a clear day how many watts would we expect to illumina
A medium is characterised by relative permittivity ε r =45 and relative permeability μ r =5. Determine the speed of e-m wave in the refractive and medium index of the medium.
Planck radiation law A law that defined blackbody radiation better than its predecessor, therefore resolving the ultraviolet catastrophe. It is depend on the supposition that e
What is the difference among isolation transformers and step up or step down transformer? Actually an isolation transformer may be physically the similar as a Step up/Step Down
please tell me some topics of biophysics.
A scalar function is given by f(x, y, z) = 2xy 2 + xyz 3 . Calculate the gradient of the function at the point (1, 1, 1).
Alloying: When an impurity atom of a different size compared to the host atom is placed into the crystal lattice, the impurity atom distorts the resin around it, either by pushing
Time constant in Inductors: It is impossible to decide exactly when the maximum point is reached on an exponential curve, or when the curve has fallen to exactly zero. To ena
