1 Process Amplifier (UPAMP) What is a process blaster? A process amplifier, also known as a process amplifier or operating amplifier, is an electronic mass that amplifies a voltage signal. The process amplifier features differential inputs, one-way output, and extremely high gain. Process amplifiers are used in many electronic applications, such as: Comparisons: The process amplifier can be used to compare two input signals and determine which one is greater. Amplification: The process amplifier can be used to amplify a weak signal. Filtering: The process amplifier can be used to filter a signal from unwanted frequencies. Integration: The process amplifier can be used to integrate a signal over time. Differential: The process amplifier can be used to figure out the difference between two signals. Oscillation: The process amplifier can be used to generate oscillating signals,
