Hi, May i know what is the function of the resistor in a Clamper circuit?
If she meant snubber, I think she would have used the phrase "Snubber" instead of clamper.Do you, perchance, mean a (dissipative) snubber circuit?
You have more faith in the erudition of 'noobs' than IIf she meant snubber, I think she would have used the phrase "Snubber" instead of clamper.
Strictly speaking, that's precisely what a 'clamper' (not to be confused with a 'clamp') is (go figure) -- FWIW I've long felt said bizarre nomenclature is cause of the considerable confusion of the terms 'Clamp', 'Clamper' and 'Snubber' (which being representative of distinct functions)... Wadda world! Wadda world!!!You call this a clamp. To me, it looks like a level shifter.
Do you need any of those LM301 or LM311H (in the fancy & trendy tin can package)? I know a guy who knows a guy.You can tell my history doesn't go back that far. When I was working on TVs I was pretty much a Tube Jockey practicing up to be a Beginner. I rarely got into the shop with the oscilloscopes so I could explore mysteries like, "How do you get a vacuum tube to set a DC level of one or two volts by working with 300 volts of supply and 20% resistor tolerance?"
I never did figure that out. I was on to the next job: precision analog design with the newfangled LM301 op-amp and some 1% resistors.
thanks for this answer. n thanks everyone too!You call this a clamp. To me, it looks like a level shifter. It changes the center of the sine wave to a more positive level. If you look from a different point of view, it clamps the most negative excursion of the sine wave.
You see that the resistor is in parallel with the diode and battery. Move the resistor to the left and see that it allows current to flow in and out of the capacitor. Without the resistor, the diode would act as a rectifier like a voltage doubler circuit and the output would become a positive DC voltage. Therefore, the resistor keeps the circuit from being merely a rectifier. The resistor and capacitor must be the right amount compared to the frequency. If there is too much resistance, the circuit will tend to be a voltage doubling rectifier. With too little resistance the output will be attenuated.
