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.
Each phase of a delta-connected load comprises a resistance of 30Ω and an 80µF capacitor in series. The load is connected to a 400V, 50Hz, 3-phase supply. Calculate (
Working: When plate potential (V p ) is positive, plate current ( I p ) flows in the circuit (because some emitted electrons reach to plate). If + V p enhances I p also increas
With the help of a circuit diagram, explain how regenerative feedback is provided in an Hartley oscillator?
What is the resistance of a coil of aluminium wire The resistance of a coil of aluminium wire at 18 ? C is 200?. The temperature of the wire is increased and the resistance
