Write an m-file "sampling.m", which will take as an input: a signal and a sampling step and will display the sampled signal and the magnitude of its Fourier transform. sampling.m
function sampling(x,step) plot(x(1:step:end),'-o') plot(abs(fft(x(1:step:end))))
use x as the input signal
x=(sin([0:pi/8:4*pi]))
Run the function with step=1.Increase the sampling step 2,4,8.... and observe what happens with the spectrum.
What happens with the spectrum as the sampling step increases?
What should be the minimum sampling frequency (maximum sampling step) of a signal?
Define instruction cycle and T-state Instruction cycle is defined, as the time needed completing the execution of an instruction. Machine cycle is defined as the time needed co
positive diode and negtive diode cliping
Transparent latch D flip Flop A typical example of this type of D flop is 7475 shown in figure when CLK connected is enable signal is high and the flip flop is enabled
Q. What is a clipper circuit? Clipping circuits are linear wave shaping circuits. The main function of 'clipper' is that it clips off a part of input waveform i.e., it cut off
Armature Reaction in DC Generator: Armature reaction is the effect of magnetic flux set up by armature current upon the distribution of flux under the main poles.
Describe, using a flow diagram, the IC design process indicating the CAD tools that could be used at the various levels.
For a vehicle suspension, a basic two-degree-of-freedom "quarter-car" model would be slightly more complicated than the spring-mass-damper system I chose to study in Figure 1. The
Q. It is desired to have a sag or tilt of no more than 10% when a 50Hz square wave is impressed on an amplifier stage. The output circuit resistance is Rv=1K. What minimum value of
Three Phase AC Circuit: Alternating circuits thus far discussed have single phase supply system and it's satisfactory for domestic application as light, fan and heating, etc.
