Abstract

In an electric signal generator capable of producing an arbitrary function by varying the slope of the output signal, a digital-to-analog converter 10 responds to programmed digital inputs from a memory 15 to provide current signals of varying amplitude to the input of an operational amplifier 20 with capacitive feedback 24 causing the amplifier to act as an integrator, thereby producing at its output a signal whose slope varies with the amplitude of the current signals provided by the digital- to-analog converter. Switches 22, 25 are provided for selecting a step-wise or slope output. Loop 40, 41, 42, 45 is for correcting zero drift. <IMAGE>
