    What a great Demonstration, makes sense now but never would have thought that's how the diode could pass the audio.

    Most excellent information RIck. I knew this was how it works, but never saw such a good demonstration. :)

    A deliberate manipulation of this effect would make some really cool sounds. Thanks Rick! Enjoyed as always.

    Good demonstration of how the current flow through a diode affects the resistance of a forward biased junction. The equivalent resistance will be approximately 26 divided by the current in milliamps. Remember that the AC amplitude will affect the current through the circuit and therefore the resistance, possibly leading to distortion of the waveform. This effect is commonly used as an amplitude control in many devices, usually by acting as a variable shunt. The more diodes in series the greater the signal voltage swing capability before distortion becomes too bad.

    I used in conjunction with capacitor in one passive crossover and the results were incredrible

    Interesting Video! So could You also make a Silicon Diode more "sensitive" (make it produce less Distortion at a lower Voltage) with DC-Biasing the Diode?

    Is the point that an audio signal voltage is established across the diode in the "restricted direction" but no current flows in that direction?

    • @AllAmericanFiveRadio
      @AllAmericanFiveRadio  Рік тому

      It's not across the diode, it's through the diode. When the diode is not biased it rectifies the audio signal. When the diode is forward biased it turns into a wire and the audio signal passes through the diode undistorted.

      @@AllAmericanFiveRadio because the biasing voltage ensures it's always conducting. And the sine wave won't cause it to close!

      @@AllAmericanFiveRadio Thanks for your reply. I used "across" to denote a voltage as opposed to a current ("through"). Forgive my possible misconceptions ... but I understand that when a "diode is forward biased it turns into a wire" but only for current in the direction of the arrowhead on the diode schematic symbol. In your measurement circuit, the audio signal current is going in the direction opposite direction.
      Is my problem that you are talking only about the diode(s) in 1) the measurement circuit used and 2) the amplifier circuit shown but we are NOT referring to the operation of diodes in general?

    I imagine people who thought it would distort were thinking about "diode clippers" that go from signal to ground like you would have in a guitar fuzz, etc.
