You would like to design the lowpass filter above that has a frequency response shown by the Bode plot below. For a lowpass filter, the passband (the frequency range where signals are passed) is at low frequencies and the stop band (the frequency range where signals are attenuated) is at high frequencies. The corner frequency marks the transition between passband and stopband. If Rf= 5000Ω you will determine the values of R1 and C to complete the design. The design is done in steps. First, determine the corner frequency (or bandwidth) in rad/sec. Enter Wb in the box below. Enter the magnitude of the passband gain, KDC. Recall that a gain in dB is related to the linear gain by the formula KdB = 20log10|k|. Enter the value for R1 in ohms . Enter the value for C in μF.
