Web10 Feb 2016 · Shannon meets Nyquist. Example: To support 16 levels (4 bits), we need a SNR of 255 (24 dB) Example: To achieve Shannon limit with SNR of 30dB, we need 32 levels. From Nyquist: From Shannon: needed to meet Shannon Limit. SNR is the S/N ratio needed to. support the M signal levels. Channel Capacity. WebThe Nyquist-Shannon Sampling theorem is a fundamental one providing the condition on the sampling frequency of a band-width limited continuous-time signal in order to be able to reconstruct it perfectly from its discrete-time (sampled) version. It stated that the sampling frequency must be at least two times the highest frequency of the ...
WebEl Teorema de Muestreo de Nyquist explica la relación entre la velocidad de muestreo y la frecuencia de la señal medida. Afirma que la velocidad de muestreo f s debe ser mayor que el doble del componente de interés de frecuencia más alto en la señal medida.
