The feedback through the RC network causes the Schmitt trigger output to oscillate in an endless symmetric square wave ( i . e ., the Schmitt trigger in this configuration is an astable multivibrator ).

In the bistable multivibrator, both resistive-capacitive networks ( C 1-R 2 and C 2-R 3 in Figure 1 ) are replaced by resistive networks ( just resistors or direct coupling ).

However, unlike the Ondes, whose oscillator is based on the theremin ( two ultra-high frequencies beating against each other, to produce a third audible frequency ), the Ondioline used a multivibrator oscillator circuit to produce its tone.

This was a monostable multivibrator, known as a One-Shot or Kipp Relay, that triggered the coarse time base, offsetting its starting point so it did not trigger immediately after the transmission, but a selected time after that.
25.
The slave's multivibrator unavoidably has analog tolerances that affect its timing accuracy, which is why the " 0 " pulses have to be 60 �s long, and the " 1 " pulses can't be longer than 15 �s.

The result of this understanding is in fact the principle behind the bistable multivibrator or flip-flop . ( Computer Circuits for Experimenters by Forest M . Mims, III, Radio Shack, a Tandy Corporation, 1974, Page 17 .)

In the last two years, I revealed, in the introductory article parts, the fundamental ideas behind such legendary circuits as RTL, Diode logic, TTL, ECL, Latch, Gyrator, Schmitt trigger, Multivibrator, Differential amplifier, Operational amplifier ( the internal op-amp structure ).

The first multivibrator circuit, the classic astable multivibrator oscillator ( also called a " plate-coupled multivibrator " ) was first described by Henri Abraham and Eugene Bloch in " Publication 27 " of the French " Minist�re de la Guerre ", and in " Annales de Physique 12, 252 ( 1919 ) ".
