Control device

Abstract

For simultaneous correction of all function adjustments of, for example, a television receiver, adjustable correcting information is stored by means of a normal function control members in a memory which is read out on operation of a function correction member.

What is claimed is: 
     
       1. Control device for adjusting at least one .Iadd.gain factor of a .Iaddend.function, which device comprises a counter having a plurality of outputs, a digital-to-analog converter coupled to said outputs of the counter and having an output, a function adjustment circuit having an adjusting signal input coupled to said converter output, a control correction member means for immediately setting said counter into a selected state, a memory means coupled to said counter outputs for supplying the digital setting for said .[.desired.]. .Iadd.selected .Iaddend. state .Iadd.to said counter.Iaddend., and a write-in control member means for providing that information from said counter outputs is written into said memory. 
     
     
       2. Control device as claimed in claim 1, further comprising a pair of gate circuits each having a pair of inputs respectively coupled to the said control members and an output respectively coupled to said counter and said memory, wherein for writing information in the memory the said two control members must be operated simultaneously, and wherein for setting the counter to the .[.desired.]. .Iadd.selected .Iaddend.state the control correction member alone need be operated. .Iadd.3. Control device as claimed in claim 1, wherein said transfer function comprises a gain control function. .Iaddend.
