Re: z-transform and DTFT
In case of DTFT of a system function, it can do the transform only if the h[n] is a stable sequence Σh[n] should be less than infinite. So we can take DTFT only for stable systems. But by using z-transform we can transform even the unstable systems and can analysis...
Re: Must i select electrical or electronics and communicatio
Hai i am doing electronics and comm final yr. i will tell u the importance of ece, then u decide urself
1. we have four main field to work on namely (1)embedded (2) core electronics (3) digital, image processing [signal processing]...
sir i am doing a project of displaying pc time in seven segment displays.
i use the parallel port to pass the bcd coded data of hour and minutes and display them by using 4 7segment displays. Here i used a bcd to seven segment decoder to convert the bcd code. now when i give the input...
Re: fourier transform
Phase : arises from phasor .
Phasor is something like a vector which is rotating (changing its angle instantaneously) so the angle it substends at present with respect to a reference phasor is the phase angle.
Now The importance of Fourier Transform:
[this is my own...
final yr project
I am doing final yr electronics and communication. i have to do a project in the field of microprocessor mostly in 8051 can any one post the address of the site which host projects/materials regarding this area
How does fourier transform transforms time to freq domain.
i know mathematically but want to know how does physically it transform what happens when the time domain signal is multiplied by exponential signal. how does the fourier arrives on that particular formula
