In the figure we have a good rectangular signals generator with several frequency bands. The circuit is based on old logic but can be implemented with modern equivalents.
This circuit produces a signal at a frequency of 455 kHz, based on a ceramic resonator CSA455E, by...
This is the traditional configuration of the 7806 as a 12 to 6 V automotive voltage reducer. The...
This instrumentation amplifier with differential inputs was found in documentation from the 90s....
