Abstract

With this binary code for video information, if it is desired to record two 0's the pulse length recorded is 2T. If it is desired to record three 0's as shown in the drawing, a pulse length of 3T is recorded. If a 1 is to be recorded, the pulse width recorded is T. The advantage of this method is that it utilizes an unclocked detector while maintaining the good resolution. Further, the modulator and demodulator can employ simple logic circuits. Single 0's are not recorded.
