ABSTRACT
Signal conditioning is essential in obtaining and improving spatial as well as energy information in radiation-detection systems. Due to the generally extremely low signal levels supplied by a radiation detector, there is a strong demand for low-noise, high-gain, unconditionally stable, and best-matched signal-conditioning components. State-of-the-art signal conditioning is still mainly based on analog devices. However, there is an ongoing trend to integrate discrete analog structures and to substitute more and more analog devices by digital methods and procedures. Although the basic principles of signal-conditioning procedures, either analog or digital, are well understood [13, 14], the ongoing progress in technology and performance also demands an improvement in the theoretical background.
