... Electronic Circuits and Components. One thing we have to be very careful about with l.e.d’s is that they are not very good at handling reverse bias, indeed if a reverse bias of more than 5V is applied to the l.e.d. then it will usually be damaged permanently. Correct identification of the anode and ...

... FXL translators offer an advantage in that either VCC may be powered up first. This benefit derives from the chip design. When either VCC is at 0V, outputs are in a high-impedance state. The control input (/OE) is designed to track the VCCA supply. A pull-up resistor tying /OE to VCCA should be used ...

Valve RF amplifier



A valve RF amplifier (UK and Aus.) or tube amplifier (U.S.), is a device for electrically amplifying the power of an electrical radio frequency signal.Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s, initially for receivers and low power stages of transmitters, transmitter output stages switching to transistors somewhat later. Specially constructed valves are still in use for very high power transmitters, although rarely in new designs.
