雙信號振鈴電路Crystal ringing circuit
晶體振鈴電路The dialing is slow and the system ca n ' t ensure the calling party fast and accurately put through the called one who is asked for receiving. 5. the bell ring is so low that the workers ca n ' t hear in the large - scaled working space with strong noise
它存在的缺點有:工程布線麻煩、費用高;電話線路成本高且利用率低;系統可靠性差;呼叫速度慢,並且不能保證主叫用戶快速、準確地找到需要接聽的被叫用戶;振鈴聲難以保證在大范圍、強噪聲的生產場所下的工作人員接聽到。The ring bell detector and the circuit which can simulate picking up the telephone have been set up in the pci demodulator. thus, automatic connection from terminal to center has been realized
現場數據採集及發送系統中設置了自動撥號電路,解調器中設置了振鈴檢測、模擬摘機電路,從而實現了終端到中心的自動連接。Control leads that come from 1a2 key telephone sets to operate features like flashing of lights to indicate on hold, line ringing, etc
控制引導,來自1a2按鍵式電話,設置用於一些操作功能,如燈的閃爍用來表示摘機或線路振鈴等等。Telephone circuit produce dtmf signal, receive ring signal and perform speech function. dtmf receiver lets it becomes binary code for mcu to read. analog circuit process speech signals between phone and gsm modem
固話電路提供產生的雙音多頻信號及振鈴和通話功能,雙音多頻收號電路將dtmf信號變成二進制碼,便於mcu的識別和處理。Then the paper dicusses the implemention of the modem based on dsp, describes the parts of the modem, design and implement the circuit of the modem ' s echo cancek ring detection -, status supervise and power supply after the detailed research on the dsp ' s performance ? function, memory space and work mode. studies the device driver of the ppsm, develops the modem ' s driver, includes the idma read and write, download page, event handle, send data and receive data
隨后,論文論述基於dsp的modem的設計,對modem的總體結構進行了描述,在對系統使用的dsp晶元adsp2187的性能、功用、存儲器空間和工作模式作了細致研究后,設計和實現了modem的回聲抑制、振鈴檢測、狀態監測和電源等硬體電路,並對ppsm操作系統下外設的驅動程序進行了研究,開發了ppsm下modem的驅動程序,包括idma讀寫、下載頁面、事件處理、發送和接收數據的程序。If stray inductance and capacitance ( which may or may not be stray ) in a circuit should form a tuned circuit then that tuned circuit may be excited by signals in the circuit and ring at its resonant frequency
如果電路中的電感和電容(含分佈電感、分佈電容)形成了諧振電路,那麼在電路中信號的激勵下,這個諧振電路就會在其固有諧振頻率處產生「振鈴」現象。分享友人
