The integrated circuits used in this oscillator are not very common today, as we obtained it in documentation from the 1980s. The circuit must be powered by a symmetrical source.
This high-gain digital amplifier uses general-purpose transistors. The supply voltage is logic...
We found this circuit in the March 1993 issue of Electronis Now magazine. The circuit uses common...
Using an LDR as a sensor and an operational amplifier this circuit was found in the Encyclopedia of...
