Device with feedback for clipping alternating-sign signals (versions) // 2607934
FIELD: radio engineering.SUBSTANCE: invention relates to radio engineering and serves to convert analogue alternating-sign signals into rectangular pulses and can be used in designing digital devices for processing signals and measuring their parameters.
