我所广大革命工人、革命工程技术人员在党的九大“团结起来,争取更大的胜利”精神的鼓午下,在毛主席继续革命学说的指导下,奋发图强,自力更生,艰苦奋斗,不怕失败。通过“实践、认识、再实践、再认识”反复试验,不断总结,在实践中提高,终于研制成了速度传感器。一、元件及线路速度传感器由叁级双稳元件,一级积分器容,一级比例放大元件组成。二、线路分析1.第一级——方波发生器(缓冲级)双稳元件右控制口加偏压后使输出稳在左边,在左控制口输入随转速变化的码盘信号,在右输出口可得到等幅不等宽方波,频率响应为:0～200赫芝2.第二级——脉冲发生器
With the encouragement of the spirit of “uniting and winning greater victories” of the 9th CPC National Congress, under the guidance of Chairman Mao’s continued revolutionary doctrine, the vast majority of our revolutionary workers and revolutionary engineering and technical personnel work hard to achieve their goal of self-reliance and hard work without fear of failure . Through “practice, understanding, re-practice, re-understanding,” repeated tests, continue to summarize, improve in practice, and finally developed into a speed sensor. First, the components and line speed sensor from the three bistable components, an integrator capacity, a proportional amplification components. Second, the circuit analysis 1. The first stage - square wave generator (buffer stage) bistable components right control port bias output to stabilize the left, enter the left control port with the speed change code signal on the right Output can be unequal width square wave, the frequency response is: 0 ~ 200 Hertz 2. The second stage - pulse generator
