Equalising harmonics generator with separate outputs - uses active pulse shaping stage for unipolar pulses of double basic frequency

摘要

The equaliser is in the form of harmonious generator for even and odd multiples of a fundamental frequency with separate outputs. The unipolar pulse frequency is twice the fundamental frequency, and is used for generating the even harmonics, while a further device generates bipolar pulses. The unipolar pulse shaping stage is followed by an amplifier, from whose output the even harmonics are collected, and by a bistable multivibrator generating symmetrical rectangular pulses. A differentiating stage and a further amplifier follow the multivibrator. the odd harmonics are collected from this amplifier output.
