How does a regenerative receiver work?
In a regenerative receiver the output of the tube or transistor is connected back to its own input through a tuned circuit (LC circuit). The tuned circuit allows positive feedback only at its resonant frequency. Regeneration can increase the detection gain of a detector by a factor of 1,700 or more.
What is the function of regenerative receiver?
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.
What is regenerative radio?
The regenerative radio was developed by Edwin H. Armstrong and patented in 1914. [ 1] The receiver uses a single vacuum tube for both amplification and detection, utilizing positive feedback to both increase the gain from a single vacuum tube and to improve the selectivity of the receiver. [
Who is legally credited with the invention of regenerative radio receivers?
Armstrong, in full Edwin Howard Armstrong, (born December 18, 1890, New York, New York, U.S.—died January 31/February 1, 1954, New York City), American inventor who laid the foundation for much of modern radio and electronic circuitry, including the regenerative and superheterodyne circuits and the frequency modulation …
Where is regenerative circuit 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.
What is electronic regeneration?
it in electrical power developing a Counter Torque, which opposes the actuator. As soon as the motor overcomes the battery it inverts the current direction and starts feeding current into the battery, while developing a counter torque that acts as a brake. This phase is called regeneration (recharging of the battery).
What is the use of regenerative circuit?
Where are regenerative circuits used?
Regenerative circuits are used to provide faster cylinder extension speeds by taking the oil from the rod end and diverting it to the head end of the cylinder. This means that the effective area during extension is the rod area that will give a faster speed but also a reduced force.
What is the principle of regenerative circuit?
Regenerative circuits save time and energy by increasing the extension speed of double acting cylinders. They do this by routing fluid exiting the rod end of the cylinder back to its cap end instead of routing the fluid to tank.

What is regenerative load?
Regenerative loads recycle the UUT output power back onto the facility or UUT in the form of re-usable electricity. This allows the test system to lower the total electrical usage while significantly reducing waste heat.
What is regenerative drive?
Regenerative drives are capable of recovering energy and feeding it back into the network so that it can be utilized by other equipment. Everything needed for regenerative operation, such as active supply unit and LCL line filter are included in the drive.
How can one transistor form the heart of a radio receiver?
Two of the transistors formed the project’s audio amplifier, leaving the radio part to just one device. How on earth could a single transistor form the heart of a radio receiver with enough sensitivity and selectivity to be useful, you ask? The answer lies in an extremely clever circuit: the regenerative detector.
How does a super regenerative radio receiver work?
A further refinement was the so-called super-regenerative receiver, in which the feedback was increased beyond the point of oscillation, but repeatedly “quenched” by an ultrasonic frequency turning on and off the regenerative detector. The simplicity of a regenerative receiver did not come without problems though.
Who was the inventor of the regenerative radio?
Chetvorno [CC0], via Wikimedia Commons. The basic regenerative receiver was patented in 1914 by the prolific inventor Edwin Armstrong, who you may also have heard of as the inventor of frequency modulation (FM).
Where is the coupling adjustment on a regenerative receiver?
The simplicity of a regenerative receiver did not come without problems though. The coupling adjustment became a small variable capacitor in later designs, and this could be found as a regeneration control on the front panel of a typical receiver.
