Thanks and please translate text, as soon as possible:
A selectable Clipper circuit restricts the signal peaks to less than twice the rms value.
The system includes a pair of tuned amplifier circuits which act as high-pass filters having a 6 decibel per octave slope from 0 to 15,ooo cycles followed by two stages, each comprised of an amplifier and clipper circuit. For converting the filtered waveform to a square wave. A radio transmitter and receiver having a plurality of separate channels within a conventional single side band transmitter bandwidth and a system for transmitting secure speech information are also disclosed.
In accordance with another specific aspect of the invention, means for converting the filtered signal to a square wave comprises at least one amplifier followed by a clipper circuit.
Diode clipper circuits can be used to limit a voltage to some maximum or
minimum value. This is useful for designing protection circuits.
The clipper circuit internal to the BH1415 will prevent overmodulation.
Thanks a lot.
