Two ends of a coil are connected to a demo galvanometer (Shelf C3-3), and a bar magnet is moved in and out of the coil, and varying speeds. One can pass a wooden ruler through the coil in the same way to show that there is no deflection wit ...

Applications of an OTA Current Controlled Amplifier
... We can manually set the control current Ictl in the CCA. The simple way to do this is with a foot operated rocker salvaged from a wah pedal, a buffering opamp to provide the current needed to drive the CCA, and a series resistor to convert the control *voltage* at the opamp output to a control *curr ...

Regenerative circuit
The regenerative circuit (or regen) allows an electronic signal to be amplified many times by the same active device. It consists of an amplifying vacuum tube or transistor with its output connected to its input through a feedback loop, providing positive feedback. This circuit was widely used in radio receivers, called regenerative receivers, between 1915 and World War II. 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. Due partly to its tendency to radiate interference, by the 1930s the regenerative receiver was superseded by other receiver designs, the TRF and superheterodyne receivers and became obsolete, but regeneration (now called positive feedback) is widely used in other areas of electronics, such as in oscillators and active filters. A receiver circuit that used regeneration in a more complicated way to achieve even higher amplification, the superregenerative receiver, was invented by Armstrong in 1922. It was never widely used in general receivers, but due to its small parts count is used in a few specialized low data rate applications, such as garage door openers, wireless networking devices, walkie-talkies and toys.
