In todays lecture, we first computed the CTFT of signal with a pure 262 hertz frequency (i.e., a CT signal that would "sound" like a middle C). We then computed the DTFT of a sampling that signal. More specifically, we used a sampling period of 1/1000. It was observed that this sampling yields a DT signal that also sounds like a middle C.
