What is samples per symbol?

Samples per symbol determine the acquisition bandwidth. The bandwidth occupied by the transmitted signal is based on the modulation type, symbol rate, and pulse-shaping filter used. To successfully perform demodulation, the analyzer must acquire the complete bandwidth.

What is electronic sample rate?

The sample rate (or sampling rate) is the number of samples taken per second. The units for sample rate are samples per second (sps) or Hertz (Hz). The two are equivalent since the Hertz is equal to the reciprocal second, [Hz]=[s-1].

What is the minimum sampling rate?

MINIMUM NUMBER OF SAMPLES

The sampling theorem states that a real signal, f(t), which is band-limited to f Hz can be reconstructed without error from samples taken uniformly at a rate R > 2f samples per second. This minimum sampling frequency, fs = 2f Hz, is called the Nyquist rate or the Nyquist frequency (6).

What are symbols in signal processing?

Symbols. A symbol may be described as either a pulse in digital baseband transmission or a tone in passband transmission using modems. A symbol is a waveform, a state or a significant condition of the communication channel that persists, for a fixed period of time.
