Band-pass Filter
A band-pass filter is an electronic device that allows signals within a specific frequency range to pass through while blocking signals outside that range. It is commonly used in audio processing, telecommunications, and radio broadcasting to isolate desired frequencies and reduce noise.
These filters are characterized by their lower cutoff frequency and upper cutoff frequency, defining the bandwidth of frequencies that can pass. For example, a band-pass filter might allow frequencies between 300 Hz and 3,000 Hz to pass, making it useful in applications like music production and signal processing.
