- Double-sideband suppressed-carrier transmission. Double-sideband suppressed-carrier transmission (DSB-SC) is transmission in which frequencies produced by amplitude modulation (AM) are symmetrically spaced above and below the carrier frequency and the carrier level is reduced to the lowest practical level, ideally being completely suppressed.

- Fanuc RS232 Settings. This Signal is set to on when the NC starts sending data and is turned off when the transmission ends. When this signal and the DSR signal are set high, the NC can send data from SD. If this signal is set low the NC will stop sending data after two more characters are sent. Jump 5 to 4 if signal isn't used.

A Beginner's Guide to Digital Signal Processing (DSP) The following document describes the basic concepts of Digital Signal Processing (DSP) and also contains a variety of Recommended Reading links for more in-depth information. What is a DSP? Digital Signal Processors (DSP) take real-world signals like voice, audio, video, temperature, pressure, or position that have been digitized and then mathematically manipulate them. A DSP is designed for performing mathematical functions like add, subtract, multiply and divide very quickly.

direct sequence spread spectrum (DSSS) or direct sequence code division multiple access (DS-CDMA) Direct sequence contrasts with the other spread spectrum process, known as frequency hopping spread spectrum, or frequency hopping code division multiple access (FH-CDMA), in which a broad slice of the bandwidth spectrum is divided into many possible broadcast frequencies.

Signal (IPC) The SIGCHLD signal is sent to a process when a child process terminates, is interrupted, or resumes after being interrupted. One common usage of the signal is to instruct the operating system to clean up the resources used by a child process after its termination without an explicit call to the wait system call. SIGCONT

Polymer Differential scanning calorimetry (DSC) measures the energy absorbed (endotherm) or produced. (exotherm) as a function of time or temperature. It is used to characterize melting, crystallization, resin curing, loss of solvents, and other processes involving an energy change. Differential scanning calorimetry may also be applied to processes involving a change in heat capacity, such as the glass transition. Similar to thermomechanical analysis, one test can generally be used to measure most or all of these properties.

Digital Signal 1 For an introduction to digital networks, see T-carrier. Digital Signal 1 (DS1, sometimes DS-1) is a T-carrier signaling scheme devised by Bell Labs. DS1 is the primary digital telephone standard used in the United States and Japan and is able to transmit up to 24 multiplexed voice and data calls over telephone lines. E-carrier is used in place of T-carrier outside the United States, Japan, and South Korea.

What is an STC Rating? What is an STC Rating? STC stands for Sound Transmission Class. Basically, STC ratings are an established way to average how much sound is stopped by something. STC ratings are used for windows, doors, walls and most building materials. For windows, STC ratings range from 18 to 38. STC ratings are the ONLY way to accurately compare various noise reduction products. An STC rating is an instrument measurement of how much noise is stopped. The STC ratings allow accurate ‘apple to apple’ comparisons. The STC rating is the average amount of noise stopped at 18 different frequencies, measured in decibels.

- Continuous Digital Coded Squelch System (CDCSS), Digital Private Line™ (DPL™), Digital Channel Guard™ (DCG™), etc. The Continuous Digital Coded Squelch System (CDCSS), was the follow-on to CTCSS (but some books use Code instead of Coded in the name). Instead of a constant low frequency tone, CDCSS superimposes a continuous repeating data or code stream of 23-bit square wave digital data words on the transmitted signal at a bit rate of 134.4 bits per second (with a tolerance of + or - 0.4 bps).
