Voltage Controlled Amplifier – VCA
https://www.electronics-lab.com/project/voltage-controlled-amplifier-vca/
The project presented here is a Voltage Controlled Amplifier (VCA). A VCA board helps users control the Audio Level from a remote potentiometer. It requires a single-ended audio signal in the input. Gain control voltage can be adjusted through an on-board potentiometer or use an external potentiometer connected to CN4. The project works with a […]
RMS Noise to DC Converter – RMS Noise Measurement
https://www.electronics-lab.com/project/rms-noise-to-dc-converter-rms-noise-measurement/
This mini-module helps users to measure the RMS noise of AC signal. Apply the AC noise signal to the input and the circuit outputs a DC voltage. Signal bandwidth is 1Khz to 100Khz and input sensitivity is 1 μVolt RMS. The LT6203 ultra-low noise, low power op-amp amplifies the low-level signal. Further, this signal is […]
