D-C amplifiers are indispensable for analog computers, measuring instruments and industrial controlequipment.One of major considerations of the amplifiers is the minimum detectable signal which usually issubject to restriction by the drift.With synchronous clamp technique, reduction of the drift can be achieved. This technique is verysimple and yet effective.This paper presents both theoretical and experimental analyses of the effect of synchronous clamp ind-c amplifiers.

Described herein is a transistorized AD/DA Converter which has both analog-to-digital and digital-to-analog conversions.In the analog-to-digital conversion, the instrument accepts 0-5V input voltages with the input impedance higher than 500kΩ and operates on them to produce 0-1000 digital output signal (real out-put is binary coded signal) in 130μ sec with accuracy and precision of 0.1%. The, operation is, of the voltage feedback encoding method.In the digital-to-analog conversion, 0-1000 digital input, signals, are converted into 0--5V output voltages with the equivalent accuracy to that of analog-to-digital conversion. Its output impedance is Iess than 1Ω.The silicon diodes are employed to gate the weighted currents in the DA conversion circuit from which feedback voltages are obtained in the analog -to-digital conversion and the output voltages in digitalto-analog conversion. As all the circuits of the instrument are carefully compensated against the temperature change, it can be used in ambient temperature 5-50°C.

In this summary of previous work, I argue that data becomes temporarily interesting by itself to some self-improving, but computationally limited, subjective observer once he learns to predict or compress the data in a better way, thus making it subjectively more “beautiful.” Curiosity is the desire to create or discover more non-random, non-arbitrary, “truly novel,” regular data that allows for compression progress because its regularity was not yet known. This drive maximizes “interestingness,” the first derivative of subjective beauty or compressibility, that is, the steepness of the learning curve. It motivates exploring infants, pure mathematicians, composers, artists, dancers, comedians, yourself, and recent artificial systems.
