This circuit uses an unusual component today which is the integrated circuit. We found this configuration in Motorola's 1990 Linear Databook.
This metal detector circuit uses an AM radio as an indicator. The radio is placed off-station and tuned...
This oscillator produces a modulated signal using a unijunction transistor. We found it in an...
This transmitter was obtained in a 1953 publication. The original transistor was made of...
