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.
(i) Conservation of charge number and mass number : In the given nuclear reaction Mass number (A) → Before the reaction After the reaction
Q. Show Conjugate Complex Poles? It is possible that some of the poles of Equation are complex. Since the coefficients ak in Equation are real, complex poles occur in complex c
Production of electricity by pressure: Certain crystals and semiconductors produce an emf between two opposite faces when the mechanical pressure on them is either increased or
Infrared Waves: Infrared wave also known as heat wave. These waves are radiation by hot body at dissimilar temperature.
Particle function: Protons The number of protons in an atom determines the kind of material: Eg. Hydrogen 1 proton Helium 2 protons Lithium 3 protons B
The mass of a mol of proton and electron is: (1) 6.023x 10 23 g (2) 1.008g and 0.55mg (3) 9.1x 10 -28 kg (4) 2gm Ans: (2) 1.008g and 0.55mg
A car travels along a horizontal circular curved road that has a radius of 600 m. If the speed is uniformly increased at a rate of 2000 km>h2, determine the magnitude of the accele
Mercury is poured into a U-tube as shown in Figure given below. 100g of water is then poured into the right hand side of the tube. The density of mercury is 13.6g/cm 3 . What heigh
With the help of a circuit diagram, explain how regenerative feedback is provided in an Hartley oscillator?
In nuclear fusion two or more than two lighter nuclei join to form a single heavy nucleus. The volume of one molecule so formed is less than the sum of the masses of parent nuclei.
