Hlavné použitie pásmového filtra

Čas: 2021-09-10 Počet zobrazení: 20

Generally speaking,a band pass filter is defined as a circuit that permits a signal to flow between two frequencies. The main function of bandpass filters is to limit the bandwidth of the output signal to the band alloted to the transmission. That is to say, the bandpass filter allows some signals to pass through while blocking others. Bandpass filters include wide bandpass filters and narrow bandpass filters. Wide bandpass filters, which are generally separate circuits for simple design and action, can be constructed as a WBF or wideband pass filter (WBF), the order of the low-pass and high-pass filters determines the order of the band-pass filter (BPF). Narrow bandpass filters, as a rule, use a lot of feedbacks. The operational amplifier is used in this band-pass filter. The difference between higher and lower frequencies is known as the filter bandwidth. These filters are mainly used to limit the bandwidth of the output signal to the band allocated for the transmission. Band-pass filters are not always necessary, but it can sometimes be used to clean up data and other applications.
