CHE SIGNIFICA PULSE CODE MODULATION IN INGLESE
Modulazione a impulsi
La modulazione a impulsi è un metodo utilizzato per rappresentare digitalmente segnali analogici campionati. È la forma standard di audio digitale in computer, dischi compatti, telefonia digitale e altre applicazioni audio digitali. In un flusso PCM, l'ampiezza del segnale analogico viene campionata regolarmente a intervalli uniformi e ciascun campione viene quantizzato al valore più vicino entro un intervallo di passi digitali. La modulazione lineare di codice a impulsi è un tipo specifico di PCM in cui i livelli di quantizzazione sono uniformemente lineari. Ciò è in contrasto con il PCM che utilizza, ad esempio, un algoritmo di legge o un algoritmo μ-law in cui i livelli di quantizzazione variano in funzione dell'ampiezza. Anche se il PCM è un termine più generale, viene spesso utilizzato per descrivere i dati codificati come LPCM. I flussi PCM hanno due proprietà fondamentali che determinano la loro fedeltà al segnale analogico originale: la frequenza di campionamento, il numero di volte al secondo che vengono prelevati i campioni; E la profondità del bit, che determina il numero di possibili valori digitali che ogni campione può assumere.
definizione di pulse code modulation nel dizionario inglese
La definizione della modulazione del codice di impulso nel dizionario è una forma di modulazione di impulso in cui l'informazione è trasportata da gruppi codificati di impulsi pcm.
