This circuit is from a documentation on the MC1539 from Motorola and may, however, be implemented with equivalent operations. The transistor also supports equivalent.
The gain of this amplifier is 10 times and the excursion to the output voltage is 6.0 V (peak to...
The frequency of this circuit depends on the crystal. The transistor supports a modern equivalent. We...
This circuit uses the SQ3524, a switching integrated circuit. The circuit was found in the April...
