Electrical delay lines for digital computer applications

A survey of existing lumped parameter and distributed parameter delay lines has shown that their maximum. storage capacity is about 23 pulses and 15 pulses respectively regardless of total delay time. An analysis of pulse transmission through distributed delay lines indicates that dissipation in the inductive elements is the chief factor limiting storage capacity. A method is proposed for decreasing this dissipation through the use of high-Q nickel zinc ferrites around straight conductors for inductive elements.
