The output of modified astable multivibrator can convey three informations simultaneously

The work presented is a study of a modified form of the astable multivibrator. The circuit presented gives a pulse frequency signal which can convey three different informations simultaneously. This simplifies the problem of transmission through overcrowded channels. The primary sensors for these informations can be voltage, potentiometric, resistive and strain-gauge-type transducers. Measurement of these informations at the receiving end is easy and simple. The transmitting and receiving circuits are realizable in the form of integrated circuits, thereby minimizing the cost and complexity of the system.
