Pulse height measurement is one of the most important step in ionizing radiation spectroscopy . However, the conventional analog and digital peak detection methods may be limited due to their high complexity and cost. In this work, a simple and novel mathematical approach based on Lagrange interpolation has been developed to precisely extract pulse height from a sequence of samples recorded at a low rate (2 MS/s). This has been implemented in an ARM-based micro-controller to construct a full functionality multi-channel analyzer. The results showed that the multi-channel analyzer has a very good integral linearity response (
