Microphone - Wikipedia
The condenser microphone, invented at Western Electric in 1916 by E. C. Wente, is also called a capacitor microphone or electrostatic microphone—capacitors were historically called condensers. Here, the diaphragm acts as one plate of a capacitor, and the vibrations produce changes in the distance between the platese are two types, depending on the method of
How to Connect a Microphone to an Arduino
Microphone Amplifier Circuit. Now that you what each of the pins of the LM386 represents, we can assemble the whole microphone amplifier circuit. The schematic for the amplifier part of the circuit is shown below: R1 is a resistor that connects the microphone to positive voltage so that the microphone is able to power on.
DIY AM Transmitter-Circuit Diagram, Components, Description
Q2 is wired as a common emitter RF amplifier, C5 decouples the emitter resistance and unleashes full gain of this stage. The microphone can be electret condenser microphone and the amount of AM modulation can be adjusted by the 4.7 K variable resistanceR5.

What Is A MEMS Microphone? (Micro-Electro-Mechanical
MEMS Microphones Vs. Electret Condenser Microphones. The MEMS microphone designed is largely based on the design of the electret condenser microphone capsule. Both mic types include the following design details: Work on electrostatic principles. Capacitor-based capsules with one movable plate (diaphragm) and one stationary plate.
How to Use a Microphone with Arduino | Microcontroller
The electret microphone is a type of condenser microphone. Condensers are essentially capacitors and condenser microphones are formed by a thin diaphragm mounted in front of a plate. Recall that a capacitor is formed by two conductors with an insulator, or dielectric, between them. Both the diaphragm and the plate are conductors.

Oct 02, 2018The gain of the circuit can be set from the R6/R5. For capacitor C3 to improve a high-frequency response better. Resistor-R9 bring a supply voltage and limit the current to connected to the circuit when the circuit for the condenser microphone. If you do not use it can remove R9 away.

Astable Multivibrator using Transistors
Nov 27, 2012R = V/Ic , where V is the voltage across the resistor R. In normal cases, V = (Vcc – Vce) = (Vce – 0.3) but when an emitter load like LED is connected, V = (Vcc – Vce – Vled) , where Vled is the voltage drop across LED. Usually the maximum collector current Ic will be much higher than than the current required for emitter load such as LED.
Telephone - Wikipedia
A traditional landline telephone system, also known as plain old telephone service (POTS), commonly carries both control and audio signals on the same twisted pair (C in diagram) of insulated wires, the telephone line. The control and signaling equipment consists of three components, the ringer, the hookswitch, and a dial. The ringer, or beeper, light or other device
