| Abstract(in English) | A new implementation of digital lock-in-amp is presented. A lock-in-amp is applied for various high precious measurement tools, such as distance meters. Lock-in-amps are now implemented on embedded processors by use of trigonometric functions and division. The proposal method employs adaptive signal processing manner in place of these computational intensive operations, so that highly precious lock-in-amp is implemented in less computational cost. The simulation result shows effectiveness of the proposed method. |
