| Abstract: | SUMMARY A circuit is described which, when fed with an alternating voltage whose amplitude may vary, produces an accurately settable, continuously variable output amplitude. The error in the output amplitude is within 0.1% for inputs from 3 V to 7 V rms, between 30 Hz and 4 kHz, and within 1% between 16 Hz and 10 kHz. By connection to this inexpensive circuit, any simple, inexpensive audio oscillator is effectively converted into a multirange, precision-amplitude ac source. |
