Found in a 90's EDN, this circuit can be used as a shield. The components depend on the MOSFETs and the load that must be controlled. The logic is TTL.
Found in an old Radio Electronics, this circuit uses common components today. The resistors of the IC...
Found in a 1965 General Electric circuit manual, this circuit uses SCRs from that time. Modern...
The modified Hartley oscillator, seen in figure 2, can generate signals ranging from 3 MHz to 10...
