This is an electronic stethoscope circuit diagram. The operation of the circuit is very simple. It's work is similar to general home audio system. The heartbeat sounds catched by electret microphone and then the amplifier amplify the signal. Component List:R1 = 10K 1/4WR2 = 2. 2K 1/4WR3, R9 = Not usedR4 = 47K 1/4WR5, R6, R7 = 33K 1/4WR8 56K = 1/4WR10 = 4. 7K 1/4WR11 = 2. 2K to .......

This unit is an updated version of the Wide Dynamic Range Field Strength Meter. While the basic function is the same, it has several critical differences: It uses a specialized integrated circuit, the Analog Devices AD8307. This chip is designed specifically as a logarithmic amplifier for use through 500 MHz. Using the AD8307, it has a wider dynamic range (85 dB versus 55 dB) and it has built-in temperature compensation. Because of the different nature of this type of detector - and the fac.......

Audioguru Circuit Description: U1a operates as a low-noise microphone preamp. Its gain is only about 3.9 because the high output impedance of the drain of the FET inside the electret microphone causes U1a's effective input resistor to be about 12.2K. C2 has a fairly hig
