Not true, the alternating signal cannot pass the capacitor or the diode. It's just that the capacitors charge and discharge, and all this works unless the signal positive wave doesn't achieve 5-0.6v, that is close to 4.4v for a standard diode.
1 For off-voltage better -5V against 0V, because you get the high transimpedance only with the hardly closed diode! 2 Better for switching 2 antiserial diodes, here switched to eachother with anodes. In this case maybe the off-voltage 0V, but the -5V better here, too. The C2 in the 2nd case is the last component of the circuit after R3.
You can also use this circuit (with other bias resistor values) in front of a transistor amplifier stage to prevent the transistor from reaching saturation. You can see it used in Joe Davisson's "Vulcan Overdrive" to achieve a less harsh distortion curve.
@@RonMattinoDon't know if you know this. I continue hearing "diet sir" instead of "diod in series", or "diet" instead of "diod". This might be just a me problem. Your accent might not be easy to ajust to.
I have heard the exact accent in other videos where i hear "Senior diet" for Zener Diode etc and the auto generated subtitles said the same. But its not hard to understand if you already know the correct words, but if you dont know the words it is maybe very hard to understand whats being explained..
5v dc act same as baising voltage us in audio amplifier. Baising voltage shift the voltage lavel. C1 stop dc to rech ac supply. And c2 fillter out dc and we get ac at output.
What will happen when AC voltage reaches 5 Vrms? Diode will be open-circuit for a short period of time correct? Also, the RC input circuit will act as a high-pass filter, so it will attenuate the input at low frequencies.
the reason for that is because AC changes direction 50 to 60 hz per second every time it goes forward then backward we count it as one cycle then there is 50/60 cycle every second so it can pass when diode is forward biased but it's blocked when it reverses direction diodes are used to convert AC to DC
As far as I know rectifier and small signal diodes are not suitable for this application. PIN diodes are good for this job

Without the DC offset, the AC voltage at the output is only half as high and it is no longer a sine wave.
Absolutely true @@lutzj74
This is a commonly used circuit, and it works well. It has limitations, but it is absolutely true!
Alternating signals pass because the capacitors DON'T charge or discharge.
It's right the opposite.@@thewhitefalcon8539

Bro do not stop add examples thanks a lot
I wish I had studied more of this in school
So u skipped classes too..
you know you can still go to school
the circuit is incompletely described at the beginning. I/O undefined, so no, you can't know what the circuit is for.
I need this all knowledge
Thank you 👍😊
Vac must be small : Vac + Vdiode (0.7) < 5V
True, but you can extend it by connecting two or more diodes in series.

Why would anyone say "diet" when explaining a circuit.. so of course he means diode. ..

@@MrDacorp Thank you.
I simulated this circuit. The input signal must be < 0.5Vp, otherwise the diode will be forced to turn on at negative cycle.
Then you are missing some parameters
Simulation isn't always accurate.
Very cool. Circuit 👍😊🇮🇪
Very informative ❤❤❤

Neat little circuit 👍🙂
What will happen when AC voltage reaches 5 Vrms? Diode will be open-circuit for a short period of time correct? Also, the RC input circuit will act as a high-pass filter, so it will attenuate the input at low frequencies.
So the output signal current source is fed from the enable node
How to know whoch values resistors and capacitors to use?
Missin 5v---20k----R1. There must be a resistive divider
Thanks man!
Can some one explain why ac voltage pass through the diode. I thought diodes only allow voltage to pass in one direction
There is five volts DC offset. The applied AC voltage at the input side is less than 5 Volts peak to peak. I hope I am correct.
It passes because the diode is already forward biased by DC voltage coming from the ON/OFF input.
the reason for that is because AC changes direction 50 to 60 hz per second
every time it goes forward then backward we count it as one cycle
then there is 50/60 cycle every second
so it can pass when diode is forward biased
but it's blocked when it reverses direction
diodes are used to convert AC to DC
That AC signal would also have a 5v DC offset (in this scenario) added to it on the output, right?
Second capacitor will cut it off.
@@pyza666 oh of course it would, I totally missed that, thanks
Cool!
What Is the purpose of ac signal switch and where it is used
antenna switches in RF for example
I want to know more details about this circuit, i have it's raw material of 10k qty. If you have a long video link share please link .
What will happen if the diode is connected in parallel?
No I cant guess the burpose of this circuit
Pin diode.
Very badly explained.
How can AC and DC in the same wire?
carefully
Not quite as you describe.
