摘要：The arrangement for a possibility that electricity is converted in proportionalelectrical signal includes the digit pulse modem of two finite resolving powers. First digitpulse modem provides period 1 pulse train, the finite resolving power withcorresponding quantizer. It may be to have ignored quantization. Second pulsedemodulator provides second round pulse train, finite resolving power and

corresponding quantizer and predetermined factor multiplied by the summation of themost pulse demodulators of quantizer. By make the second pulse train

durchgeschalteten umber of pulse and pulse sum ratio be equal to the predetermineddurchgeschalteten factors inverse, umschaltanordnung alternately by the impulsiveswitched of two clocks be mittelungsschaltung. Mittelungsschaltung is the Gleich. exceptdurchgeschalteten pulsesMittelung improves resolution ratio compared with the finiteresolving power of digit pulse modulation.
