The idea is a new principle of an A/D converter based a natural phenomenon. It consists of a circuit producing spike pulses proportional with the input signal. The second circuit consists of counters and a control unit which controls the counter circuits depending from the input parameters. The spikes are counted independently from each other from a given moment for a specified time interval.

Suppression of the frequency is technically justified which is bigger than half of the sampling frequency. A weak element in a signal transmission system is the analog-digital transformer, because the low-pass filter function leaks at certain frequencies and so the signal transmission becomes distorted. This has significance in sound transmission and high-precision measurement, where it results in errors.

 The solution relates to an analog to digital transformer the sample-taking procedure and assembly from circuit elements of which differs from the usual. The BADC is suitable for realizing a very precise, noise-free low-pass filter during analog to digital transformation, furthermore the user can set the parameters of measurement. Thus in terms of implementation this technical solution clearly has the better quality clearly.
