Design on Imitate the quantity processing to deliver to receive the system for the infrared speech of numerical quantity
Abstract
This text introduces to imitate the quantity the processing delivers the basic structure of receive the system for the red foreign language sound of numerical quantity, analyzing to design the audio frequency signal before collecting the electric circuit, signal placed the big electric circuit, frequency to make the electric circuit, red shot the electric circuit outside, red circumscribed to accept the electric circuit, four operated to enlarge the electric circuit, frequency solution to adjust the electric circuit and voice revivification electric circuit etc. was each to constitute the part.The article elaborated to use to press to control the frequency vibration machine( from lock mutually the frequency that wreath constitute makes the electric circuit) to carry on principle and characteristicses that makes the electric circuit to the speech signal generally, and from homologous lock mutually the wreath electric circuit leads the principle and the characteristics that the feet exportation follows to input the signal frequency to carry on the frequency solution to adjust the electric circuit.Fore place the audio frequency power to enlarge to used a passage low electric voltage audio frequency power to enlarge the electric circuit in the electric circuit, used the LM567 in general use audio frequency decoding machine in frequency make reach agreement adjust electric circuit, after receiver electric circuit placed the big part and solutions to adjust before the audio frequency signal enlarged the electric circuit to adopt the LM324 four lucks to put the integrated circuit。
Keywords: The frequency make;The frequency solution adjust;Place before greatly;Four operations enlarge
