Data Acquisition - ADCs/DACs - Special Purpose

ADCs Stands for Analog to Digital Converters. It is an electronic device that receives analog signals and converts these signals into digital form. An example of an ADCs is a microphone that collects sound data from the outside world and converts the signals into digital or computer format.

Digital-to-analog converters abbreviated as DACs are components in electronic machines that work as a converter of digital signals into analog signals respectively. An instance of DACs is a communication device such as a modem which requires DAC equipment that converts digital signals into analog signals which are functional through the cables of a telephone connection.

Importance of ADCs/DACs:

One of the major importance of ADCs/DACs is that without ADCs/DACs components electronic machines will not be able to communicate with the outer world, therefore it is important for an electronic device that it must have an ADCs/DACs component built into it, to communicate with the outside world. ADCs/DACs components work as agents that build the connection between an electronic machine and the outer world to effectively communicate with one another to convert analog signals into digital form and digital signals into analog form.

Types of ADCs/DACs- Special Purpose:

There are several types of ADCs/DACs that are implemented according to their function and need, some of their types are discussed below:

Crosstalk

In the field of electronic equipment, the crosstalk is every fact by which every wave, which is transferred from one station to another in a transmission system generates an unwanted impact on the other station or channel, usually caused due to unwanted conductive coupling from one station or circuit to the other. Crosstalk is a huge concern in communication systems, auditory electronics, organised wiring,  ICs, and radio communication.

Aperture Jitter

Aperture jitter is also known as aperture or uncertainty in a model-to-model alternation commonly quantified in Root-mean-square rms or picoseconds. Its scale of the linked productivity inaccuracy is connected to the ratio of alteration of the given analog input.

Acquisition Time

The acquisition time is the timespan/interval throughout which open (FID) free induction decay is to be stored. Along with all the techniques that are used to recognize signals, the time that is needed to record the signal is said to be acquisition time.

Application areas of ADCs/DACs- Special Purpose:

At this stage of life in the modern era, electronic machines are widely used in different fields, such as Hospitals, Business, Transportation, as well as Entertainment, and many more. Therefore ADCS/DACs components are particularly important in electronic devices. Some other applications of ADCs/DACs are given below:

• Computer and Smartphones 
• Microcontrollers
• Headphones and Microphones have ADCs/DACs built into them
• Modems and other communication devices
