SODOP Algorithm as a Principle for the Design of the Ambient Noise Controlled Amplifier

The oscillatory response due to the positive feedback of the ANCA (Ambient Noise Controlled Amplifier) in the changing high background noise environment is corrected with the Static-On/Dynamic-Off Page (SODOP) algorithm for the amplifier gain. The SODOP algorithm principle is based on the constant background noise measurements and the dynamic change of the amplifier gain in the periods of page-off, and the static constant amplifier gain during page-on. A hardware version of ANCA with the SODOP algorithm was developed confirming advantages of SODOP version in comparison to presently available ANCA's, particularly where it is impractical or impossible to provide diapason of minimum and maximum background noise during amplifier calibration.
