audio sweep generator

elektor electronics november 1985 by P Theunissen This sweep generator is intended primarily for use with the Function Generator described in the December 1984 issue of Elektor Electronics, but can also be used with other types. It varies the output frequency over a predetermined range of values so that the two units together can be used to investigate the behaviour and frequency response of, for instance, an electronic filter or amplifier. Fig.1 Block schematic of the sweep generator. When the sweep generator is used with a function generator other than that described in the December 1984 issue of Elektor Electronics, it should be noted that the VCO must be capable of operation over an input voltage range of 0.1 V to 10 V, corresponding to a frequency ratio of 1:100. If not, a suitable level adapter should be used. Block schematic The generator provides the signals that are necessary to display, for instance, the fre- quency response of a filter on...
