18/05/2021A low pass filter is a filter which passes low-frequency signals and blocks, or impedes, high-frequency signals. Low pass filters can be constructed using resistors with either capacitors or inductors. A low pass filter composed of a resistor and a capacitor is called a low pass RC filter. 2.

The external RF filter response is highly dependent on both the system SFDR targets and the SFDR performance of the ADC itself; an analog filter tool can help there during the design phase. A decimation filter spur locator tool helps in situations where unwanted spurs in the fast Fourier transform (FFT) spectrum occur during system bring-up.

Half-band filters are lowpass FIR filters with cut-off frequency of one-quarter of sampling frequency f s and odd symmetry about f s /4 [1]*. And it so happens that almost half of the coefficients are zero. The passband and stopband bandwiths are equal, making these filters useful for decimation-by-2 and interpolation-by-2.
