bandpass filter function
解釋
帶通濾波器函數-
Butterworth - type and bessel function - type two ways are used for design of bandpass filter for receiver, and with the help of eda simulation tools, the bold plot and the group delay characteristics of the filters designed are compared
摘要採用巴特沃思型和貝塞爾函數型2種方法進行接收機帶通濾波器設計,藉助eda對該濾波器進行波特圖和群延遲特性的比較。 -
The main work of the system can be divided into four main parts as the following : ( 1 ) 10. 5ghz bandpass filter the main contradiction of filter is caused by its function of dividing frequencies. in order to properly divide frequencies, not only need passband ’ s attenuation to be as small as possible and stopbands ’ as big as possible, but also need a sharp and quick change between the attenuation of passband and stopband, thus to make their diversity obvious
這四個功能模塊分別是: (一) 10 . 5ghz帶通濾波器濾波器的主要矛盾是由它分隔頻率的功能決定的,為了使分隔理想,一方面要求通帶的衰減盡可能小,阻帶衰減盡可能大,亦即通帶和阻帶的衰減差值要盡量大;另一方面要求通帶和阻帶之間衰減的變化應盡可能快,最好是陡峭的跳變,使阻帶和通帶的分隔十分明顯。
