A description is given of the theory, operating characteristics, and maintenance procedures of an analog Limiter for repetitive computer use. The Limiter has greater accuracy and flexibility than the earlier model. It utilizes a bridge-type diode circuit and is capable of generating the following functions 1 Symmetric Limit with variable limits, 2 Asymmetric Limit with variable symmetry, 3 Asymmetric Limit with variable peak to peak limits, 4 Asymmetric Limit with a separately variable limit, The variation of the control dials necessary to generate these functions does not cause the output dc level to change, unless the origin is intentionally placed beyond the linear portion of the limit characteristic. Device errors are discussed and experimentally verified. The device was constructed using a standard operational amplifier similar to those in use in much of the repetitive computer. Author
