Se ekipman elektrik lou itilize nan prèske tout jaden. Analog Convertisseurs dijital (ADC) ak dijital konvètisè analog (DAC) se eleman esansyèl pou nenpòt ki varyasyon nan DSP nan nenpòt ki jaden. De interfaces konvèti sa yo nesesè pou konvèti siyal reyèl sou latè yo pou pèmèt ekipman dijital elektwonik yo ranmase nenpòt siyal analòg ak pwosesis li. Pran yon mikwofòn pou egzanp: ADC la konvèti siyal la analòg kolekte pa yon D 'nan ekipman odyo nan yon siyal dijital ki ka ekate pa oratè oswa monitè. Pandan ke li ap pase nan ekipman odyo a nan òdinatè a, lojisyèl ka ajoute eko oswa ajiste tèmpo a ak ton nan vwa a yo ka resevwa yon son pafè. Nan lòt men an, DAC pral konvèti siyal la deja trete dijital tounen nan siyal la analòg ki itilize pa ekipman odyo pwodiksyon tankou monitè. Anba la a se yon figi ki montre ki jan egzanp anvan an ap travay ak ki jan siyal odyo opinyon li yo ka ogmante nan repwodiksyon, ak Lè sa a, sorti kòm siyal dijital nan monitè.

Electric equipment is heavily used in nearly every field. Analog to Digital Converters (ADC) and Digital to Analog Converters (DAC) are essential components for any variation of DSP in any field. These two converting interfaces are necessary to convert real world signals to allow for digital electronic equipment to pick up any analog signal and process it. Take a microphone for example: the ADC converts the analog signal collected by an input to audio equipment into a digital signal that can be outputted by speakers or monitors. While it is passing through the audio equipment to the computer, software can add echoes or adjust the tempo and pitch of the voice to get a perfect sound. On the other hand, DAC will convert the already processed digital signal back into the analog signal that is used by audio output equipment such as monitors. Below is a figure showing how the previous example works and how its audio input signals can be enhanced through reproduction, and then outputted as digital signals through monitors.
