ABSTRACT:
In the method of attenuating or amplifying digital signal values as described herein the desired modification is realized in two steps.
A coarse attenuation or amplification in steps of 6 dB is effected by shifting the digital word to be modified into a shift register (R), after which fine amplification is realized by adding the word, which is attenuated by shifting it a number of times, to the word thus shifted. Furthermore, a device for carrying out said method is described, in which the signal processing section only comprises one shift register (R) and an adding circuit (AD), the additional shift being achieved by means of the wiring between the said shift register (R) and the adder circuit (AD), so that no further signal-processing registers are required for carrying out the said cumulative addition.
