Title: Equaliser for non-sinusoidal distortion - has four terminal network bypass to existing unit which does not affect transit time
Inventor: HAEGELE WALTER DIPL ING
IPC: H04B3/14
Filed: 1976-04-13
Abstract: An equaliser circuit is applicable to the correction of non-sinusoidal distortions without introducing an additional transit time delay and with practically unity transfer constant in the operating frequency range. It is designed as a band-pass or all-pass four-terminal network with a frequency-dependent transit time which is converted to a non-sinusoidal frequency characteristic of the equaliser in a by-pass coupling (U). The four-terminal network (L) may form part of the normal communication channel and the by-pass coupling (U) may consist of a four terminal network with a transfer phase angle 0 or 180 deg., or + 90 deg. By using part of the communication channel, such as a four-terminal network already existing in the equipment, and bridging it by a suitable unit, a very simply realised equialiser is obtained without disturbance of transit time.
