Abstract: 1495730 Analogue-to-digital and digital-to-analogue conversion SOC DES PROCEDES MODERNES D'INJECTION SOPROMI 5 Dec 1974 [7 Dec 1973] 52671/74 Heading H3H [Also in Division G3] A variable mark-space ratio signal for controlling an internal combustion engine is obtained from voltages representing water and air temperatures which are alternately converted to digital signals and thence to the required mark-space ratio signal, which is of constant frequency and has alternate cycles dependent on the water and air temperature respectively. As shown, multiplexor 1 alternately connects the water and air signals to an analogue-to-digital converter comprising a comparator stage 4 in which the input voltage is compared with a descending ramp voltage to form a pulse-duration signal enabling a gate 5 to pass clock pulses to a frequency-division stage 6. This comprises two divide-by-p counters (16, 17) for water and air respectively whose overflow outputs are connected to a counter (18) to derive binary signals A and B and an overflow signal C<SP>1</SP>, which together with the multiplexing control signal C address a programmed memory 7 which delivers an 8-bit word to preset a counter 8 which delivers a constant frequency mark-space ratio signal S in which the duration of the mark is the time taken for fast clock pulses H to cause counter 8 to overflow. The divideby-p counters are not reset, the remainders being carried forward to the next conversion cycle.
