Microphones
- Electret Condenser Microphone (ECM): Low cost, requires bias voltage, commonly used in consumer electronics.
- MEMS Microphone: Integrated preamp and ADC, digital or analog output, compact size, ideal for smartphones and IoT devices.
- Dynamics Microphone: Rugged, no power required, used in live audio and high-SPL environments.
- Condenser Microphone: High sensitivity and wide frequency response, needs phantom power, used in studios.
Key Parameters: Sensitivity, SNR, Frequency Response, Impedance, Power Supply Requirements.
