<p>S01278 S80P25 AM DETECTING CIRCUIT A single-ended push-pull amplifier converts a single-ended input into a balanced signal which, after amplification, is fed to the bases of alternately operating transistors, and the resulting inverted, or out-of-phase output currents of the inverting transistors are fed back to almost exactly equal the signal current fed to the amplifier. The base drives required to produce such fed-back currents are also fed to the bases of output driver circuit transistors where a full-wave rectified replica of the input signal is produced. -i-</p> |
