COMBINED INTERPOLATION & ON-CHIP ANALOG FILTER RESPONSE
filter characteristics and the X-axis of the response plots have been normalized to the sample rate (Fs) and can be
referenced to the desired sample rate by multiplying the given characteristic by Fs.)
Notes: 2. Referenced to a 1 kHz, full-scale sine wave.
