parametron Electronics.|pəˈræmɪtrɒn|
[f. parametric a.1 + -on; coined in Jap. by E. Goto 1955, in Denki Tsūshin Gakkai Zasshi XXX. 770.]
A digital storage element consisting of a parametric oscillator in which the digit is represented by the phase (0° or 180°, corresponding to 1 or 0) of the output signal relative to that of an applied reference signal of the same frequency.
1956ETJ of Japan June 64 A new type of electronic computer component called the ‘parametron’ was invented by Ei-ichi Goto of the Faculty of Science, University of Tokyo, in spring of 1954. 1957Jrnl. Sci. Res. Inst. (Tokyo) LI. 59 (caption) A parametron unit; an exciting current is supplied from 1, causing an oscillation in the L-L′-C circuit. Input and output lines are 2 and 3 respectively. 1960T. E. Ivall Electronic Computers (ed. 2) xiii. 234 The parametron requires no valves or transistors, only passive reactive elements, and being therefore extremely stable, reliable and long-lived, is ideally suited for use in digital computers. The main limitation is that because several cycles of oscillation are required to establish a binary digit,..the digit rate is necessarily low. 1967R. K. Richards Electronic Digital Components & Circuits vi. 337 Parametrons quickly became very popular with Japanese computer manufacturers... However, not one computer employing parametrons is known to have been built or designed in the United States. |
