An active low-pass filter is an electronic circuit that allows low-frequency signals to pass through while attenuating or blocking high-frequency signals. It is called "active" because it employs active components, usually operational amplifiers (op-amps), to achieve its filtering function. In an active low-pass filter, the output voltage is low (closer to zero) for high-frequency input signals and rises towards the maximum value for low-frequency input signals. Here's a basic circuit diagram of an active low-pass filter using an operational amplifier: ``` ``` Explanation of the circuit: 1. **Vin**: This is the input voltage signal that you want to filter. It is connected to the non-inverting terminal of the operational amplifier. 2. **Vout**: This is the output voltage of the low-pass filter. It is taken from the output terminal of the operational amplifier. 3. **R1**: This is a resistor connected in series with the input signal. It sets the input impedance ...
