dc.description.abstractLock-in amplifiers are instruments widely used in physics and engineering laboratories, whose invention goes back to the 1940s. Due to the late electronic developments, the former analog implementations have been replaced with digital versions, mainly based on FPGAs (field-programmable gate arrays). The present work, exploiting the last advances in the microcontrollers field, consists in the development of a functional prototype of a low-cost lock-in amplifier based on a microcontroller with similar specifications to mid-range commercial amplifiers. The performance of the prototype has been tested and compared with commercial devices, showing a similar performance in common use cases at a much reduced cost.en
