Found in a 1968 American documentation, this circuit generates sawtooth signals whose rise and fall times are determined by C1 and C2. Transistors support modern equivalents.
This circuit converts square (rectangular) signals into triangular signals with typical 16 V...
The transistors of this circuit found in an English 1980s documentation may be the modern BC548...
In the figure we have an AND gate with the LM3900 operational transconductance amplifier. The...
