Active Lowpass Filter: This is a 1st-order active low-pass filter using an op-amp. The input passes through an RC network (1 kΩ and 1 µF), which sets the cutoff frequency at 159Hz. The op-amp provides buffering and gain without loading the RC stage. At 10 Hz input, well below cutoff, both input and output signals closely follow each other, indicating minimal attenuation. As the input frequency increases, the attenuation increases and the output signal amplitude reduces. #electronicsrd #Electroni
