Continuous - time filter needn ’ t a / d switch, data processing, d / a switch technique and so on to finish filtering function with analog signal like digital filter. and it needn ’ t switch action to sample data in the discrete time with analog signal like switched capacitor filter. so continuous - time filter has several advantages, such as high processing speed, simple circuit configuration, and low power consumption
對每種方法都進行了詳細的推導，總結了每種設計方法的設計步驟、適用場合，舉例用每種設計方法對具體濾波器進行了電路設計、靈敏度特性分析、失真特性分析等，並用計算機模擬驗證了電路方案。 -
Hi1 port of the packed switched network and that of circuit switched network have the same data structure, also about hi2 port. however, delivery of packetized content of communication ( hi3 port ) shall not use no. 7 signal system but tcp / ip
包交換域和電路交換在hi1和hi2介面上傳輸的數據格式相同，二者hi3介面實現不同，在包交換域中採用tcp ip協議進行傳輸包交換域的偵聽內容。 -
The switched - current ( si ) circuit reported by j. b. hughes et al. in 1989 is the current domain sampled - data system
開關電流電路是1989年由hughesj . b .等人提出的。 -
Mobile phones with packet - switched communication appear to be " always connected " to the data network, whereas in the case of circuit - switched connections, setup time takes around 30 seconds to connect from a mobile phone to an isp
具有分組交換通信功能的手機似乎「始終連接」到數據網路，但是，對于電路交換連接，設置時間大約需要30秒才能將手機連接到isp 。 -
Even on circuit - switched networks, applications start immediately since they reside on the phone ? with no need to wait for a data call to be initiated
即便是在電路交換網路之中，應用也可以即刻啟動，因為這些應用安裝在本機上?需與遠程服務器交換數據，這樣就避免了電話網路的繁忙對于使用的影響。 -
Csd circuit switched data
電路交換數據 -
The limited number of sites and unattractive charges are problems arose in the process of operators and icps deploying the service and the restrictions on the terminals mostly refer to the small - sized displays of the handsets and the inconvenience of entering characters through the keyboard, which are manufacturers problems. as to slow connectivity, it seems to be the weakness of wap. however, the fact is that there is a limit of 9600 bits on the circuit - switched data services provided by the gsm network and this is the very bearer mode that is currently selected by wap established on the network layer. this only means that people do not accept wap over csd
站點少、資費並不具吸引力等缺點是運營商與icp在對該業務推廣的過程中所顯現的問題；來自於終端的限制則是手機製造商的問題，雖然各大廠商都推出了支持wap的手機，但用戶的批評大都集中在手機屏幕太小及輸入不方便；至於連接速度慢，這似乎是wap本身的缺陷，但事實是gsm網路所能提供的基於電路交換的數據業務存在9600bits的限制，而建立在網路層之上的wap目前選擇的恰恰是這種承載方式，因此只能說wapovercsd這種業務提供模式人們不能接受。 -
While data over gsm is circuit - switched and occupies a channel irrespective of usage, data over gprs is an always - on, packet - switched data stream where users pay according to usage
盡管gsm上的數據是線路交換的並且不管怎樣都佔用一個通道，但是gprs上的數據是一直連接的（ always - on ） 、分組交換（ packet - switched ）的數據流，用戶根據使用付費。
