Abstract
Most code modulation systems involve complicated circuits. In order to avoid this disadvantage, ternary code modulation system has been developed. Codes of this particular system have a kind of ternary signals that are plus and minus pulse train and zero level signal. The plus pulse train occurs when the signal variation is over a unit level, minus pulse train when under unit level, and zero signal when equals to unit level. These ternary signals are made up simply of feedback integrator and trigger circuit. This system has the following advantages: (1) Circuit device is very simple, (2) Multi-channelizing is very easy and (3) Signal to noise ratio is improved in comparison with ΔM system. This system has a wide application in the field of applied physics such as in telemetering or remote controlling.
