Digitization of Audio Samples Audio signals are continuous in time and amplitude Audio signal must be digitized in both time and amplitude to be represented in binary form. Discrete in time by sampling – Nyquist Discrete in amplitude by quantization Once samples have been captured, they must be made discrete in amplitude.

Fundamentals of Multimedia, Chapter 6. The graph in Fig. 6.1 has to be made digital in both time and amplitude. To digitize, the signal must be sampled in each dimension: in time, and in amplitude. (a) Sampling means measuring the quantity we are interested in, usually at evenly-spaced intervals.

Rotary Head Digital Recorders Thus the bandwidth channel capacity of the recorded signal can be seen to be related to tape speed: the faster the speed, the higher the frequency that can be recorded Digital video and digital audio need considerably more bandwidth than analog audio, so much so that tape would have to be drawn past the heads at ...

SIGNAL PROCESSING is the analysis, interpretation and manipulation of like sound, images, time-varying measurement values and sensor data etc. Types of signal processing: 1. Analog signal processing 2. Digital signal processing 5. DIGITAL SIGNALPROCESSING: DIGITAL: Operating by the use of discrete signal to represent data in the form of numbers.

The ratio of the power of the correct signal and the noise is called the signal to noise ratio (SNR) | a measure of the quality of the signal. The SNR is usually measured in decibels (dB), where 1 dB is atenthofa bel. The SNR value, in units of dB, is de ned in terms of base-10 logarithms of squared voltages, as follows: SNR =10log 10 V 2 signal V 2 noise =20log 10 V
