Abstract

1434028 Spectrum analyzer DEFENCE SECRETARY OF STATE FOR 11 Jan 1974 [15 Dec 1972] 58006/72 Heading G1U In a spectrum analyzer an input signal can either be passed via a tunable band-pass filter Fig. 2, and then sampled at regular intervals, digitized, entered into a circulating store the contents of which are read-out repeatedly, converted to analogue form and displayed on a c.r.o, or the input signal, Fig. 3, can be sampled at regular intervals, digitized, entered into a circulating store the contents of which are read-out repeatedly, converted to analogue form, and then passed via a tunable band-pass filter to a c.r.o.
