  • EMI Filters and RFI Filters-Image
    EMI Filters and RFI Filters - (345 companies)
    Electromagnetic (EMI) filters and radio frequency interference (RFI) filters purify signals of unwanted noise by attenuating the high-frequency RFI (typically 150kHz and up) and passing the low frequency EMI. Electromagnetic interference (EMI...

  • Passive Filters-Image
    Passive Filters - (19 companies)
    Passive filters are implemented using only passive components such as resistors, capacitors and inductors. These filters do not produce any amplification of the input signal. Passive filters use only passive electronic components: resistors...

    Active Low Pass Filters - (23 companies)
    Butterworth filters are designed so that the frequency response is flat in the passband. Chebyshev filters feature a very steep roll-off but have ripples in the passband. Elliptic filters (or Cauer filters) exhibit equalized ripple in both the passband...

    Active Band Pass Filters - (21 companies)
    A constant group delay in a filter's passband implies that for all signals with frequencies in the passband, the time delay will be the same. This fact is especially important in audio, video, and radar applications. Butterworth filter. Butterworth...
