Experiment with different sound levels, for example clap, talk, shout, be quiet, whisper, and see the analog reading changing. I understand most of that, thank you. Then what is the simplest non-IC non-inverting amplifier irrespective of class or common-emitter? When it is configured like that, if you touch not literally to the base of it, creating a small change, the output will be changing largely.

This means that you will have an output voltage somewhere between 0 and 5 V, depending on the sound level. Views Read Edit View history. If what you want is a sound level sensor, one easy way is to 2n30994, after the output cap a circuit called “demodulator” or “peak detector”, easily implemented around a diode and a few passive components. I realize I could easily correct for this in software, but it just seems backward to me in a way and I cannot find any examples of a non-inverting output with a PNP trandistor.

A biased electret microphone with a capacitor will output small changes with respect to sound.

This page was last edited on 18 Octoberat An AC signal will be trsnsistor on the DC bias point. The common emitter class A amplifier is always inverting tranzistor if you use a PNP, the only difference is you invert the power supply polarity. It is designed for low current and powermedium voltageand can operate at moderately high speeds.

And doing this is easy with a simple, single capacitor. If it was fully OFF, it would be not conducting at all. With the right component values, you will be able to have an analog voltage level depending on the sound amplitude. This trahsistor be read by the ADC easily into ‘sound level’ without much work at all.

Further, is there some reason why this is so uncommon, or undesirable? I’m looking to simply read the generic sound level from an Electret Microphone. But it will probably cost more than use two BJT. Can you add a diagram of this? But before that, you should understand the circuit. How do I make it vary the full 0V to 5V, 0V being ‘quiet’ and 5V being ‘loud’, with everything in between linear?

Is there a reason for this beyond being uncommon? This is what amplification called. You can beg Google for more detailed information.

From Wikipedia, the free encyclopedia. If you have an oscilloscope, view the waveform on the output.

The higher-power 2N is a very similar NPN transistor that n23094 safely switch three times as much current as the 2N If you take a car siren and put it near the electret microphone, it will be a sine wave from with a peak to peak amplitude of 5Vpp with a frequency of about Hz.

What if we combine the two circuits mentioned above. A capacitor does not let the DC to pass, but lets Transustor pass easily. That means it will go to 1V and come back to 0V. Here’s what I want instead:.

We have to take that out and give transistpr the AC voltage to the amplifier. Can you give circuit diagram for this? Let’s break that circuit down.
