What is a super regenerative receiver?
What is a super regenerative receiver?
The super regenerative receiver is based on the simpler regenerative radio. It uses a second lower frequency oscillation within the regeneration loop that interrupts or quenches the main RF oscillation. The second or quench oscillation typically operates at frequencies above the audio range, e.g. 25 kHz to 100 kHz.
How does a regenerative receiver work?
The regen receiver operates by introducing positive feedback into the receiver circuit. This positive feedback dramatically increases both the gain and selectivity. The RF amplifier has a feedback loop that feeds a proportion of the output back to the input so that the signals around the loop are in phase.
How do you tune a regenerative receiver?
To do this, hook up your receiver and plug in a coil that covers a frequency somewhere in the 3 MHz to 6 MHz range. Set the antenna coupling to the middle of its range and then turn up the volume. Slowly turn up the regeneration control until you hear a gentle “plop” or an increase in the hiss in the headphones.
What is the main advantage of regenerative circuit?
Advantages of regenerative receivers include increased sensitivity with modest hardware requirements, and increased selectivity because the Q of the tuned circuit will be increased when the amplifying vacuum tube or transistor has its feedback loop around the tuned circuit (via a “tickler” winding or a tapping on the …
Where are regenerative circuits used?
A regenerative circuit can be used to cause a cylinder to extend more rapidly than it could with pump oil flow alone. The rod end of the cylinder is connected to the main pressure line, so the oil which normally would be discharged to a tank will join with the pump oil, increasing the speed of the piston.

When was the regenerative receiver invented?
1912
The regenerative receiver was invented in 1912 and patented in 1914 by American electrical engineer Edwin Armstrong when he was an undergraduate at Columbia University. It was widely used between 1915 and World War II.

What is a regeneration valve?
They allow the connection between rod and base of an hydraulic cylinder. They permit the movement reversal using a pressure signal.
