Lecture 6: Sampling and Aliasing

The sampling frequency or sampling rate, fs, is the average number of samples obtained in one second, thus fs = 1/T, with the unit samples per second, sometimes referred to as hertz, for example e.g. 48 kHz is 48,000 samples per second . Reconstructing a continuous function from samples is done by … See more 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 See more In practice, the continuous signal is sampled using an analog-to-digital converter (ADC), a device with various physical limitations. … See more When a bandpass signal is sampled slower than its Nyquist rate, the samples are indistinguishable from samples of a low-frequency alias of the high-frequency signal. That is often done purposefully in such a way that the lowest-frequency alias satisfies the See more Complex sampling (or I/Q sampling) is the simultaneous sampling of two different, but related, waveforms, resulting in pairs of samples that are … See more Functions of space, time, or any other dimension can be sampled, and similarly in two or more dimensions. For functions that vary with time, let S(t) be a continuous function (or "signal") to be sampled, and let sampling be performed by measuring the … See more Audio sampling Digital audio uses pulse-code modulation (PCM) and digital signals for sound reproduction. This … See more Oversampling is used in most modern analog-to-digital converters to reduce the distortion introduced by practical digital-to-analog converters, such as a zero-order hold instead of idealizations like the Whittaker–Shannon interpolation formula.
