What is it about?

It is shown here through mathematical derivation and numerical simulations how to recover, in real-time, the true physical data waveform hidden in the "distorted" output waveform of an electromagnetic and mechanical transducer (including pre-amplifier) with arbitrarily high-order transfer characteristics, possibly using modern DSP/FPGA and ADC/DAC technology.

Why is it important?

Conventionally, the useful bandwidth of a transducer-amplifier system is restricted to the flat part of its transfer characteristics. Using this technique, it is possible to extend it far beyond, restricted only by the DSP/FPGA's bandwidth.


It was a pleasant surprise to earn the Editor's Pick of the prestigious instrumentational journal with a mathematical paper.
