What is Analog Input?
Analog input refers to the process of converting a physical signal into an electrical signal. This process is called analog-to-digital conversion (ADC). The goal of ADC is to convert a continuous signal into a discrete signal that can be processed by electronic devices.
Types of Analog Inputs
There are several types of analog inputs, including:
- Voltage Input: This type of input converts a voltage signal into an electrical signal.
- Current Input: This type of input converts a current signal into an electrical signal.
- Frequency Input: This type of input converts a frequency signal into an electrical signal.
Analog Outputs
Analog outputs refer to the process of converting an electrical signal into a physical signal. This process is called digital-to-analog conversion (DAC). The goal of DAC is to convert a discrete signal into a continuous signal that can be processed by electronic devices.
Types of Analog Outputs
There are several types of analog outputs, including:
- Voltage Output: This type of output converts an electrical signal into a voltage signal.
- Current Output: This type of output converts an electrical signal into a current signal.
- Frequency Output: This type of output converts a frequency signal into a voltage signal.
