Abstract

1,123,193. Measuring circuit characteristics. MULLARD Ltd. 6 May, 1966 [14 July, 1965], No. 29848/65. Heading G4H. In apparatus for measuring the electrical transfer characteristic of a circuit in a desired frequency band, input pulses having an energy spectrum including said band are generated repetitively and applied to said circuit, the waveforms of the input pulses and output pulses from said circuit being approximately reconstituted on an extended time scale by sampling successive input and output pulses, the samples then being digitized. Thus the samples required at successive points within the typical input (or output) pulse are obtained from respective successive (identical) versions of the pulse. The digitized samples are used by a computer for Fourier analysing the input and output pulses to derive their amplitude and phase components, the ratio of respective amplitudes (input and output) and the difference of respective phases being obtained. The group time delay (rate of change of phase with frequency) can also be calculated.
