Audio Signals … An audio signal is a representation of sound, typically as an electrical voltage. Audio signals have frequencies in the audio frequency range of roughly 20 to 20000 Hz (the limits of the human auditory system). Audio signals may be synthesized directly, or may originate at a

Digital Coding is essential in the design and implementation of HDTV: • Composite Coding (sampling of the composite analog video signal i.e. all signal components are converted together into a digital form) is the straightforward and easiest alternative, but: cross-talk between luminance and chrominance in the composite signal

Abstract. In many instances it is more appropriate to describe audio signals as some function of frequency rather than time, since we perceive sounds in terms of their tonal content and their frequency representation often offers a more compact representation. The Fourier Transform is the basic tool that allows us to transform from functions of ...

S-Video(Separated video, e.g., in S-VHS) -- a compromise between component analog video and the composite video. It uses two lines, one for luminance and another for composite chrominance signal. Analog Video Analog video is represented as a continuous (time varying) signal; Digital video is represented as a sequence of digital images NTSC Video 525 scan lines per frame, 30 …
