Abstract: |
|||
| The present invention relates to a kind of voltage-controlled variable resistor. It adopts analogue storage technology and its resistance value may be freely set up and kept up for a relatively long time. It can carry out the synchronous infinitely variable control for multiple singnal channels and has the advantages of without contact noise, without mechanical wear, without regulating and controlling dead center, simple circuit, convenient operation, good sealing, low cost and small size etc. It is applicable to the volume and tone control of acoustical appliances, such as TV, recorder, amplifier, electronic organ, toy, etc. and the singnal control of other electronic equipments. | |||
