EE5410 Signal Porcessing --The trade-off of FIR filters

Wan Chin:
這群與中共同謀的奸猾之民，只會用盡力量逃來香港及扼殺香港，卻毫無勇氣與中共對抗，反而希望兩邊利益盡取：

取得香港護照及福利保障，但不離開大陸的資產累積和工作機會。

請對中共及大陸人同時死心吧。他們不是同胞，是共產黨的同謀。

雖然我覺得武力絕對唔係一個好既解決方法. 但絕不能放棄在最後最後使用,
放棄呢個可能性,只會永遠比人食住.

就好似小國擁有攻擊性而不是防禦軍事設備, 雖然如果一打扙好可能會滅國,

但係別人知道, 你最後有寧為玉碎, 不為瓦全既決心, 反而得到和平;尊重及合理既對代.

For FIR filters, one of the principal trade-offs between the time and frequency domains is that increasing the flexibility in specifying the frequency domain characteristics of the filter,

including, eg., achieving a higher degree of frequency selectivity, requires an FIR filter with an impulse response of LONGER duration.

Nonrecursive filters CAN have exactly linear phase.
