Found in a 1968 EEE, this circuit uses transistors from that time. The output is 300 ns. Transistors can be replaced with modern equivalents.
Found in National Semiconductor publication from the 1980s. This gain-100 circuit can be...
We found this configuration in a 1975 publication. It can be implemented easily, as it uses only...
The high number of transistors on this radio for the medium wave range is an indication of its...
