Hello, I have attached a circuit diagram to amplify an electret mic (suitable for feeding into a Picaxe chip.
I am trying to understand the function of each of the components.
Can someone please help me with the following:
- What is the purpose and method of calculating the 10K and 1M ohm resistors ?
Also, I understand that the .1 microfarad capacitor is there to block unwanted DC noise. Is .1 a standard value to use or was it calculated somehow ?
Thanks kindly for any help.
