Lecture - 8 Discrete Time Fourier Transform

[rooyresh]

Good evening sir.. Can i know what is the application which is using DTFT?

[rajatkmitra]

I stand corrected.....see the previous lecture about 24 minutes into it...the professor derives an FIR recursively....similarly it is clear that at IIR can be derived non recursively...

[rajatkmitra]

By definition IIR is a recursive filter !!! FIR's are not recursive....

[chingkui]

I don't think an IIR filter can be implemented non-recursively, can anyone give me a counter-example?

excellent



[rajashraful]

You are excellent sir. I like your favorite upsampler too!

Sir You are an amazing Teacher..I have started loving DSP bcoz of u..I am really thankful to those who have uploaded vdo lectures for this course....

the indian universities always have such class animations

[alex3ff4rly]

is it just me or does this guy look like an indian Bill Murray?

[kzawy]

@alex3ff4rly he does! :D

[approachapp]

@alex3ff4rly I would have said Stevan Segal

[approachapp]

Stephan Segal

this lecture contains

1)conditions for fourier transform

2)examples of discrete fourier transform

3)properties of fourier transform

Did you know that if you take the Fourier Transform of milk you will get paneer?

[lilhalosoldier]

thank you

In the example that was give, there is a mistake in the sequence. It should be symmetrical x[n]= [1/4,1,7/4,0,-7/4,-1,-1/4]
