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.
A small ball with a mass of 60.0 g is loaded into a spring gun, compressing the spring by 12.0 cm. When the trigger is pressed the ball emerges horizontally from the barrel ata hei
I want to measure H, not B The magnets in question are permanent magnets (large Neo or SmCo magnets), not coils ============================== Steel _______
what is the time period of a liquid in U tube ?
(i) Electric field lines come out of positive charge and go into the negative charge. (ii) Tangent to the field line at any point gives the direction of the field at that point.
How do you calculate tensile strength? Tensile strength isn't really measured; it's calculated. It is explained as the point at which a sample of material fails when subjected
in water equivalent how the temperature or water and solid equal?
Are the optics efficient as a means to transport the light? No, optics is not efficient as a means to transport the light. If we take any other means of light distribution or
Frequency:- The number of vibration done per second by an oscillation body is known its frequency. It is denoted by V. The S.I unit is Hz.
One of the Maxwell's e-m equations involves the curl of the electric field. Write down the equation and mention the law of electromagnetism which is shown by the equation.
