Analog Signal Conditioning topics include: Signal conditioner, operational amplifier, noise reduction, bridge circuits, converters like current to voltage, voltage to frequency and vice versa.
Signal conditioning is the process of manipulating analog signals to prepare them for further processing. Signal conditioners are an essential part of a system that interfaces with a sensor.
Signal conditioning includes: Signal isolation: Protects sensitive equipment from potential hazards that may come through the signal path from the sensor. Preprocessing: Includes signal preprocessing and removal of undesirable signals. Linearization: Converts a non-linear input signal to a linear output signal. This is necessary when sensors produce signals that are not linearly related to the physical measurement. Amplification: Increases the input signal strength or amplitude. This can increase the resolution of the measurement. Analog-to-digital conversion (ADC): Changes a continuously variable, or analog, signal into a multilevel digital signal without altering its essential content.
Signal conditioners accept inputs such as: DC voltage and current AC voltage and current Frequency Electric charge
