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.
Q Calculate the longest wavelength that can be analysed by a rock salt crystal of spacing d = 2.82 Ao in the first order. Data: d = 2.82 Å = 2.82 × 10-10 m; n = 1 ; λmax = ?
In the mass spectrograph, two positively charged ions having the similar velocity pass through a slit and enter a uniform magnetic field at right angles to their initial velocities
The physical value which does not depend on any other physical quantity is known as a fundamental physical quantity like length; mass and time are known as fundamental units.
P-Type Substance: When a small quantity of boron or Indium (group III A elements ) is added to silicon or Germanium, holes are formed in it and it becomes good conductor of pos
initial position time the vibration mean time time period of the bob t time
Explain about the principle of acousting grating. Acousting Grating Principle: While ultrasonic waves are passed by a liquid, the density of the liquid varies layer by layer
Explain about the double-crucible method. Low loss fibers are mostly manufactured by using double crucible and vapour phase deposition method. The double-crucible method is
UNIT AND DIMENSION OF DISPLACEMENT. The S1-unit of displacement is metre (m). The dimension of displacement is [L] or [M o LT o ]
A thin uniform rectangular sign hangs vertically above the door of a shop. The sign is hinged to a stationary horizontal rod along its top edge. The mass of the sign is 2.40 kg and
Who are the best system integrators? Being fairly the opposite of fiber optics manufacturers, system producers are generally small companies. In this case size has the opposite
