Algorithms, loops, "if" statements - these are words computer programmers use all the time. But what do they actually mean? We've asked a computer science professor to break it down in simple terms. | CBC News: The National

📌In signal processing, sampling is the reduction of a continuous-time signal to a discrete-time signal. A common example is the conversion of a sound wave to a sequence of "samples". A sample is a value of the signal at a point in time and/or space; this definition differs from the term's usage in statistics, which refers to a set of such values. A sampler is a subsystem or operation that extracts samples from a continuous signal. A theoretical ideal sampler produces samples equivalent to the i
