WebNote that, ideally, these low-pass filters should be ideal, meaning they should be brickwall filters. This is typically achieved (approximately) by a LPF with a sinc impulse response. De-Emphasis Filters. De-emphasis filters are used in systems where pre-emphasis and de-emphasis are needed for improved signal transfer. WebExample: 60 dB attenuation, F s =100KHz, F p a s s = 1KHz, F s t o p =3KHz. N t a p s = 60 22 ∗ 2 / 100 = 137 taps (rounding up) Playing around with these numbers can also demonstrate the significance in processing reduction by using decimation approaches.
