Analog Computer developed at Radio Physics Dept by Dr Arun Kumar Choudhury

Choudhury was instrumental in building the first analog computer in India. He is best known for his work on optimization of Switching Circuits,

High Threshold Logic High-threshold logic (HTL), also known as ''low-speed logic'' (''LSL'') or ''high-level logic'' (''HLL''), is a variant of diode–transistor logic used in environments where noise is very high. Operation The threshold values at the input to a ...

, unate-cascade realizability and fault-tolerant synthesis of sequential machine. A list of Choudhury's publications may be found here and here. Each year, lectures on Computer Science are arranged in memory of Choudhury's achievements. The Information Technology College at Calcutta University is named after Choudhury.
