Title:
DIGITAL SIGNAL WAVEFORM SHAPING CIRCUIT
Document Type and Number:
Japanese Patent JPH05226986
Kind Code:
A
Abstract:
PURPOSE: To recover a digital signal into an original signal with less error even when the waveform of a digital signal is deteriorated due to a narrow frequency band caused by the convenience of the economy of the transmission system and a rectangular wave is unsharpened and deteriorated like a sine wave.
CONSTITUTION: The circuit is featured such that a deteriorated waveform signal is amplified and clipped by linear C-MOS inverters A1, A2, A3 and shaped and recovered into a digital waveform equal to that of the original signal in the space transmission of the digital signal such as the 1-bit PWM or PDM system, etc.
