Abstract
PURPOSE:To perform a multiple-gradation display of 2<n> by a simple constitution, by selecting a pulse corresponding to n-number bits after converting an input signal to the n-bit digital signal and generating a display signal pulse and performing amplitude modulation. CONSTITUTION:In this case, pulse width generator circuit 19 generates modulating pulse width signals t0, t1...t7 and strobe signal ts in parallel by the trigger input from timing control circuit 9. That is, monostable multivibrators 21 to 29 are provided with variable resistances VRS, VRO to VR7 and capacitors Cs, C0 to C7 respectively, and can adjust output pulse width ts, t0 to t7 independently of one another. Then, in general, after the input signals s converted to a n-bit digital signal, a pulse corresponding to the n-number bits is selected. Then, a display signal pulse is generated to perform amplitude modulation, so that a multiple-gradation display of 2<n> can be performed by a simple constitution.
