Aside from having a redesigned case and a more integrated motherboard, the SL and TL each offered improved video hardware capable of graphics, on-board Hercules Graphics Card compatible monochrome video offering resolution, and an improved sound circuit featuring an 8-bit mono DAC / ADC.

The ADC / DAC, which became known as the " Tandy DAC " in games that supported it, was broadly similar in function to sound devices which connected to the parallel port ( such as the Disney Sound Source ), but unlike those devices it was integrated onto the motherboard, supported DMA transfers and could sample at frequencies up to 48 kHz.

In 1953, B. Smith showed that a nonlinear DAC could result in the inverse nonlinearity in a successive-approximation ADC configuration, simplifying the design of digital companding systems.

* Analog to Digital / Digital to Analog ( ADC / DAC )

| ADC / latch | | DAC |

The lifecycle of sound from its source, through an ADC, digital processing, a DAC, and finally as sound again.

In other words, it contains both an Analog-to-digital converter ( ADC ) and Digital-to-analog converter ( DAC ) running off the same clock.

Each recorder consisted of a modified IVC model 826P open-reel 1-inch VTR, connected to a custom codec unit with time code capability ( using a proprietary time code developed by Decca ), as well as outboard DAC and ADC units connected to the codec unit.

It had an on-chip ADC / DAC with an internal signal processor, but it didn't have a hardware multiplier and was not successful in the market.

DAQ cards often contain multiple components ( multiplexer, ADC, DAC, TTL-IO, high speed timers, RAM ).

Waiting for a trigger, starting the ADC, looking up the time, waiting for the ADC to finish, move value to RAM, switch multiplexer, get TTL input, let DAC proceed with voltage ramp.

family were built on the EMU10K1, came standard with four-channel analog audio outputs, and the ubiquitous 15-pin MIDI / Joystick multiport, and similar AC ' 97 architecture ( isolation of ADC / DAC functionality into a separate codec chip.

The cards use the new integrated Sound Core3D chip, which features the Quartet DSP from the X-Fi series as well as integrated DAC, ADC and I / O interface in a 56-pin package.

This zero-order hold effect is a consequence of the hold action of the DAC and is not due to the sample and hold that might precede a conventional ADC as is often misunderstood.

The non-linearities of either ADC or DAC are analyzed by replacing the ideal linear function mapping with a proposed nonlinear function.

This includes analog-to-digital conversion ( ADC ), digital-to-analog conversion ( DAC ), storage, and transmission.

The argument is that a softmodem isn't a real modem at all, but rather a simple electrical interface between computer and phone line, limiting itself to very basic functions such as voltage / current adaptation and functioning essentially as a DAC / ADC, much like a sound card which handles pure PCM and analog signals from and to the telephone line, while the host's CPU does the actual job of synthesizing or analyzing all necessary waveforms ( carrier, dialing tones ) and applying all necessary DSP techniques ( FSK, QAM, PSK etc.

* Empia EMP202 ( 2 channel, 20-bit DAC and 20-bit ADC, full duplex AC ' 97 2. 2 compatible stereo audio CODEC )

* A combination ADC and DAC would technically be an endec, though they are usually called CODECs

In this, the ' ranging ' was to be applied to the analogue signal before the analogue-to-digital converter ( ADC ) and after the digital-to-analogue converter ( DAC ).
