Signal reproducing circuit |
摘要 |
An improved high boost circuit for a reproduced frequency modulated video signal is disclosed, wherein the third harmonic components of the reproduced f.m. video signal is suppressed, so that the undesired so-called over-modulating effect causing signal inversion is avoided at the boundary of different video signal levels.
