21. He was a prolific inventor with 107 US patents among others logic circuits for arithmetic. 22. Using logic gates with higher fan-in will help reducing the depth of a logic circuit . 23. In logic circuits , it decreases the noise immunity; in power applications, it increases the dissipated power. 24. Transistorized computers could contain tens of thousands of binary logic circuits in a relatively compact space. 25. Univac TRANSTEC " test " transistorized computer with plug-in logic circuit board using Philco surface-barrier transistors. 26. Static relays may be based on analog solid state circuits, digital logic circuits , or microprocessor-based designs. 27. These logic circuits are known as computer memory. 28. Hazards are a temporary problem, as the logic circuit will eventually settle to the desired function. 29. The power supplies of adiabatic logic circuits have also used circuit elements capable of storing energy. 30. The Dutch researchers, like Lieber, have built logic circuits to perform each of the fundamental operations.
