Digital recording

View this topic in
In digital recording, the analog signal of video or sound is converted into a stream of discrete numbers, representing the changes in chroma and luminance values (video) or air pressure through time, thus making an abstract template for the original sound or moving image. Beginning in the 1980s, music that was recorded, mixed and mastered digitally was often labelled using the SPARS code to describe which processes were analog and which were digital.

An Implantable 64-Channel Wireless Microsystem for Single-Unit Neural Recording

Sodagar, A.M.; Perlin, G.E.; Ying Yao; Najafi, K.; Wise, K.D. Solid-State Circuits, IEEE Journal of, 2009

This paper reports an implantable microsystem capable of recording neural activity simultaneously on 64 channels, wirelessly transmitting spike occurrences to an external interface. The microsystem also allows the user to examine the spike waveforms on any channel with 8 bit resolution. Signals are amplified by 60 dB with a programmable bandwidth from < 100 Hz to 10 kHz. The input-referred ...


Companding Digital Signal Processors

Klein, A.; Tsividis, Y. Acoustics, Speech and Signal Processing, 2006. ICASSP 2006 Proceedings. 2006 IEEE International Conference on, 2006

We discuss a technique whereby internal signals in a DSP can be controlled externally without causing output disturbances. This is used to extend the technique of companding (compressing and expanding), widely used in transmission and sound recording, to digital signal processors. It is shown that this technique allows all signals involved, including those at the input of an analog-to-digital converter ...


A digital VCR deck mechanism using new precision actuators for high density recording

Mori, K.; Tomita, M.; Shige-eda, T.; Kokubo, K.; Nakagawa, K.; Nagasawa, M.; Yokoyama, E. Consumer Electronics, IEEE Transactions on, 1993

A VCR deck mechanism using high-performance actuators has been developed for high-density recording. ME (metal-evaporated) tape and laminated Sendust heads are used to raise the linear recording density, a moving-head actuator permits narrow track recording and playback, and thin tape media of 8 μm thickness are employed. The track density is 4200 TPI when the recording wavelength is 0.53 μm. ...


High-resolution digital holography applied to micro-structure measurement

Baoqun Zhao; Aili Qin; Huaying Wang Control and Decision Conference, 2009. CCDC '09. Chinese, 2009

Digital holography has been demonstrated to be a useful tool in metrology. In this paper, the theoretical-limited resolution of digital holographic imaging system without pre-magnification is presented. The recording condition of off- axis lensless Fourier transform digital hologram is analyzed briefly. By using an automatic aberration compensation procedure proposed by T. Colomb, the computer simulation and the experimental investigation of ...
