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.
