ABSTRACT:
A hybrid analog function generator producing an adjustable time delayed analog output signal varying in predetermined non-linear relationship with an analog input signal wherein the analog input signal is converted to a first digital signal addressing a programmable read only memory which is programmed to produce a second digital signal, corresponding to the predetermined function of the analog input signal, which is converted to a proportional analog output signal and wherein a selected digital number can be added to the first digital signal and wherein the quotient of a first analog input signal divided by a second analog input signal can be converted to the first digital signal and wherein an analog output signal can be generated which is proportional to the second digital signal multiplied by a third analog input signal.
