We found this circuit in a 1977 documentation. The National Semiconductor's LM380 is no longer easily found, but if used on this amplifier it provides excellent reproduction quality.
Found in a 1968 publication, this circuit generates signals with the waveforms shown next to the...
We found this circuit on Motorola Linear Interface ICs from 193. Other circuits in the series can...
In the figure we show a Varicap-controlled VCO capable of generating signals in the range of a few...
