The Spectrum of Sampled Signals 

Hey Barry, I guess the equation of the summation of sampled cosines at 10:13 needs a small correction. In the green equation, the second term still has "t" instead of "n" which multiples with (-fk Ts ). If I am wrong please let me know. Cheers!

you are the only one on the whole internet that is teaching this thing, if not you then I would have been doomed.

I appreciate your video. This is a further step after understanding Eular relationship and Fourier Series. Great! Thank you!

do you always try to restrict f^ between 0.5 and -0.5 or was that just something specific only for this example? Thanks

Well shown, thank you!

My brain cannot understand this im really bad at everything I have no basic math

can you make a video showing the relation between the driscrete and continuos spectrum?

Amazing, Thank you!

Consider an arbitrary signal g(t) comprising of sinusoidal functions, where arguments can be in any form of your choice. Now this g(t) is passed through a sampler for sampling at a rate of nHz, assume values for n. For each case sketch the sampled signal ,sketch the spectrum of sampled signal ,also explain whether you can recover the signal g(t) from the sampled signal? If the sampled signal is passed through ideal low pass filter of nHz sketch the spectrum of the output signal, assume values for n as per your choice. Justify how vital sampler in digital communication is, also state what did you infere about the signal g(t). Bro plzzz sent answer for this sir????
