multiar Electronics.|ˈmʌltɪɑː(r)|
[f. multi- + ar, of unknown origin.]
A circuit which produces an output signal when a varying voltage applied at one input exceeds an adjustable constant voltage applied at a second input, and which consists of a simple regenerative circuit with a diode and a pulse transformer in the feedback loop.
1946Jrnl. Inst. Electr. Engin. XCIII. iiia. 321/1 The Multiar.. may be made to generate a delayed marker by utilizing the time-base waveform itself. Ibid. 1197/2 Two or more complete pick offs of the type described can be operated from a single sawtooth without mutual interaction, and for this reason the circuit is often called the ‘Multiar’. 1953Electronic Engin. XXV. 404 The discriminators consist of ten multiars, each with an individual H.T. supply. 1965Millman & Taub Pulse, Digital & Switching Waveforms xvi. 625 The tube multiar is not useful for positive-going signals because multiple oscillations are obtained. However, a multiar constructed with a p-n-p transistor can be used if the input is a positive-going signal. |
