In electronics signal conditioning means manipulating an analog signal in such a way that it meets the requirements of the next stage for further processing. The most common use is in analog-digital converters. In control engineering applications, it is common to have a detection step (consisting of a sensor), a signal conditioning stage (where signal amplification is normally performed) and a processing step (usually performed by an ADC and a microcontroller). Operational amplifiers (operational amplifiers) are commonly used to carry out signal amplification in the signal conditioning stage. In some transducers this characteristic will be inherent, for example, in lobby effect sensors.
In Power Electronics prior to processing sensed input signals by sensors such as the voltage sensor and current sensor, these are reduced to the level of the microprocessor using the signal condition card. Signal inputs accepted by signal conditioners include DC voltage and current, AC voltage and current, frequency and electric charge. The sensor inputs can be accelerometer, thermocouple, thermistor, resistance thermometer, strain gauge or bridge, and LVDT or RVDT. Specialized inputs include encoder, counter or tachometer, timer or clock, relay or switch, and other specialized inputs. The outputs for signal conditioning equipment can be voltage, current, frequency, timer or counter, relay, resistance or potentiometer, and other specialized outputs.
