What is it about?

An adaptive oscillator is constructed that can be used as an analog frequency analyzer. The circuit described is for a field-programmable analog array, which can be quickly prototyped. This system has a wide variety of applications, ranging from robotics to harsh environment signal processing.

Why is it important?

An adaptive oscillator can do signal processing, similar to an FFT. However, it takes less computational resources, since it is a simple analog circuit.


Adaptive oscillators can be used for many environments, in which computational power is limited.
