/pəlst/

Origin: Formed within English, by derivation. Etymons: pulse n.², -ed suffix²; pulse v., -ed suffix¹.

Etymology: Partly < pulse n.² + -ed suffix², and partly < pulse v. + -ed suffix¹.

1942 Radiation Lab. (Mass. Inst. Technol.) Man. No. m-15 (title) Spectrum analyzer (Type 103) for pulsed oscillators at 3,000 Mc/sec.

1978 R. V. Jones Most Secret War ii. 16 In 1931 W. A. S. Butement and P. E. Pollard..had devised and made a pulsed radio system on a wavelength of about 50 centimetres for detecting ships.

1996 Independent 13 Aug. ii. 7/1 Britain follows guidelines issued by the European Federation of Societies for Ultrasound in Medicine and Biology which advises against the use of pulsed Doppler devices in the first three months of pregnancy.

2005 New Scientist 12 Feb. 75/2 (Advt.) We are studying the magneto-optical properties of..metal clusters using magnetic circular dichroism (MCD), absorption and pulsed EPR spectroscopy.

1947 Proc. Physical Soc. 59 958 The form of the initial frequency modulation before the oscillator settles down to its ultimate frequency is now of great interest, particularly in the case of pulsed transmissions.

1957 F. Hoyle Black Cloud ix. 182 We ought to start sending pulsed messages on the one centimetre [wave-length].

1981 M. S. Longair High Energy Astrophysics xvi. 221 The simplest solution is that the magnetic axis of the pulsar is not aligned with the rotation axis so that beamed radiation from the polar regions will cause pulsed emission to be observed.

1990 Physiotherapy 76 745/2 An alternative strategy was developed..of applying either pulsed electric fields, or pulsed magnetic fields, across the defect.

Compounds

pulsed column n. Chemistry and Engineering a column used for solvent extraction in which the flow of solvent and feed liquid is disrupted by a mechanically or pneumatically induced pulsing action, which promotes mixing of the two phases (cf. mixer-settler n. at mixer n. Compounds).

1958 Engineering 14 Feb. 205/3 In the solvent extraction processes..the solvent is dispersed and caused to contact the aqueous phase by flowing counter-current in the process units, which may take the form of packed columns, pulsed columns or mixer-settlers.

1978 Nature 23 Mar. 298/3 Because oxide fuel is highly radioactive, the process is carried out in pulsed columns (rather than mixer settlers) to minimise the contact time between the solvent and the dissolved acid fuel.

2004 Jrnl. Chromatogr. 1040 64/1 Columns in common use can be divided into two general groups: 1. Intensified columns using energy to provide a high degree of contact between the two phases (rotating disk or impeller columns, pulsed columns.., [etc.]).

pulsed Doppler adj. Electronics designating or relating to (esp. radar or ultrasound) techniques which make use of Doppler effects on reflected pulses of radiation (cf. pulse-Doppler adj. at pulse n.² Compounds 2).
