Abstract : An analog storage system has been designed using delay line techniques. The analog storage is accomplished by comparing the analog voltage to be stored with a voltage ramp in a comparison circuit; when equality between voltages is found an output signal from the comparison circuit triggers a monostable multivibrator which has the same period as the voltage ramp. The monostable multivibrator is made to retrigger by using feedback to control the gating of a trigger pulse. The system is capable of storing any voltage between approximately +10 volts and -10 volts to an accuracy of 1% of the full range. Several possibilities for the storage circuit are investigated.
