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. In the given circuit, calculate the current through the circuit and mention its direction . Let the current be I. 5I + 10 I + 5 I = 10 + 20 that is 20 I = 30 Current I =
SQUIDs, or super conducting Quantum interference devices are used to measure minute changes in magnetic flux by means of a pair of Josephson junctions, often used to detect extrem
With the help of relevant diagrams, define the following terms: (i) Pulse-position modulation (PPM) (i) Pulse-duration modulation (PPM)
Q. Describe the method of measurement of the thickness of a thin transparent mica slit using Fresnel's Bi-prism. Give necessary theory. Draw suitable diagram. Measurement of
a loaded cart has a mass of 227kg. if a 312n force acting at an angle of 30degree to the ground is applied. how much work is done in moving the cart 15meters?
Draw a graph showing the variation of binding energy per nucleon with mass number for dissimilar nuclei. Describe, with the help of this graph, the release of energy by the process
The neutrons and protons in a stable nucleus are held together by nuclear forces and energy is required to pull them infinitely apart (or the similar energy is released during the
Unit of Charges: The S.I unit of charge is Coulumb represented by "c".
show that in a glass prism that the refractive index n = sin1/2(A+Dmin)/sin1/2A where a = refracting angle. hence if the angle of incidence i on oan air boundary is 60degrees. calc
