High Density Pcm Magnetic Tape Recording
The Bell & Howell Enhanced-NRZ recording reproducing technique for bit packing densities up to 40,000 per track inch is described in this paper. Utilization of the pulse code modulation format of Enhanced-NRZ achieves this high density with a bit error rate of one in ten million. Bell & Howell’s standard VR-3700B instrumentation tape recorder and wideband instrumentation recording tape are used...

Recording and processing spontaneous, human-to-human conversations in natural settings is a far more challenging task. Face-to-face meetings are not only challengin...
متن کاملAudio Watermarking Based on PCM Technique
Digital instruments come to be used in Desk Top Music (DTM), live performance, etc. These performances are recorded as digital contents, and circulated actively through network and electronic media. Digital Water mark technology paid much attention to solve the problem of illegal distribution & duplication when the digital contents are spread over electronic media. In this paper, we focus on a ...
