Non-linear analogue-digital converter |
摘要 |
A non-linear analogue-to-digital converter having analogue-to-digital conversion relation curves on the basis of which the conversion is carried out and which curves can be freely exchanged. The converter comprises a gate pulse generator circuit for producing gate pulses of a predetermined duration, an oscillator for producing a signal of a variable frequency in response to a signal representing an input analogue quantity in which an element for varying analogue-frequency relation is incorporated, a counter for counting the signal from the oscillator during the duration of the gate pulse signal, and an arrangement for controlling the converter in accordance with pre-determined patterns in dependence on the count value of the counter.
