For the sampling theorem the goal is to convert a bandlimited CT signal x(t) to a DT sequence xnby sampling at rate Fs such that x(t) can be reconstructed exactly from xn.

▷ Control activity at ASEA. ▻ Central laboratory Aage Garde/Erik pitch and panning control - fulfills Nyquist–Shannon sampling theorem - in trial version up to 1 kHz - fast signal calculation - detailed user stable by Nyquist Theorem. 5. Givet en integrerande regulator C(iω) = 1. Tiiω och ett system med frekvensfunktion G(iω) = 2.

From the opposite point of view, the sampling rate must be greater than twice the highest frequency we wish to reproduce.* This frequency, half the sampling rate, is often called the Nyquist frequency.

The Nyquist Theorem, also known as the sampling theorem, is a principle that engineers follow in the digitization of analog signals. For analog-to-digital conversion (ADC) to result in a faithful reproduction of the signal, slices, called samples, of the analog waveform must be taken frequently.

The Nyquist Sampling Theorem states that: A bandlimited continuous-time signal can be sampled and perfectly reconstructed from its samples if the waveform is sampled over twice as fast as it's highest frequency component.
