Baseline regenerator for high-rate PCM signals - has differential amplifier combining amplified input signal with averager output

摘要: The baseline regenerator has an ac-coupled input amplifier (V1) and a differential output (V3). adds the amplifier's to of averager. latter consists two amplitude detectors (D1, C1, R1/D2, CR, R2) detecting positive negative amplitudes respectively coupled at their inputs amplifier. outputs are combined by narrow-band with gain 1/2. limiting characteristics. impedances average magnitude. Time constant have no adverse effects.
