Breakpoint frequency

  1. Nov 10, 2005 #1
    How do I derive the equation of the breakpoint frequency f = 1/2*pi*R*C for a high active filter and a low active filter? Do I use Vin/Vout?

    R= resistance
    C = Capacitance
    Vin = Voltage input
    Vout = Voltage output

    The breakpoint is the frequency where the reactive impedance [tex]j2\pi fC[/tex]is equal in absolute value to the real impedance R.
