This is because of the capacitors. IF you transishor talking about DC levels the question is still unclear. Maybe you should try to make the supply voltage 5V.

Transiwtor, is there some reason why this is so uncommon, or undesirable? Then, read the analog value on the collector of Q1. Also, wouldn’t the peak detector vary between Can you give circuit diagram for this? What you’ll have at the output is AC, a capacitor blocks DC.

Ehryk Nope, the output will be somewhere transitor 0 and 5V. This transistor is low-cost, widely available and sufficiently robust to be of use by experimenters and electronics hobbyists.

If you use an audio transformer instead of a capacitor you could change the signal phase as you please. Let’s break that circuit down. From Wikipedia, the free encyclopedia. Here’s what I want instead: Experiment with different values thanthen report me the results.

However, my comment above ignores the DC offset. We have blocked the DC portion of the voltage on the electret microphone. You will probably need electrolytic capacitors. This page was last edited on 18 Octoberat But someone correct me if Tranzistor am wrong, but your schematic shows a simple biased amplifier, so you would really have 2.

This is what amplification called. See this page for more info on two stage, and non-inverting transistor amplification. It seems that you want an AC level which diminishes in magnitude as the input voltage increases.

As far as I understood, you are trying to make some kind of a sound level detector, which will let you detect if there is a sound with a certain volume or not. Also, transstor that there is no more an output capacitor.

When there is a whisper, the peak to peak transistr will be about 1Vpp with changing frequency because of the speech. The same value resistors and capacitors, the same 2n transistor, added to the output of your existing schematic, would provide a second inversion.

Imagine that there is nothing else but the below schematic:. It is used in a variety of analog amplification and switching applications. The 2N is used very frequently in hobby electronics projects, including home-made ham radioscode-practice fransistor and as an interfacing device for microcontrollers.

How do I make it vary the full 0V to 5V, 0V being ‘quiet’ and 5V being ‘loud’, with everything in between linear? The common emitter class A amplifier is always inverting even if you use a PNP, the only difference is you invert the power supply polarity.

Then what is the simplest non-IC non-inverting amplifier irrespective of class or common-emitter? Felice Pollano 5 Yes, but a diode will drop 0. It looks like I want the above with an envelope detector, however that would only get me from 0V to 2.

That means it will go to 1V and come back to 0V. This means that you will have an output voltage somewhere between 0 and 5 V, depending on the sound level. In other projects Wikimedia Commons. You can use values up to uF.

Experiment with different sound levels, for example clap, talk, shout, be quiet, whisper, and see the analog reading changing. If hransistor is not the case, can you please explain “I’m not looking for a logicthe Arduino’s analog inputs have a bit ADC that gives for 0V-5V, respectively” in this context.

AC is what I’d be looking for there, right? Have a look at this. You can beg Google for more detailed information.
