双极性或单极性的方波信号在进行一些仪器仪
表研发中经常用做信号源或作为仪表电路中的使用
信号。传统的运放或其他模拟器件构成的方波信号
电路存在着方波频率准确度不高、频率范围较窄及
占空比较难调准等问题。-Bipolar or unipolar square-wave signal of the instrumentation to carry out R & D are often used as a signal source or the use of instrument-signal circuits. Conventional operational amplifier or other analog square wave signal circuit consisting of the existence of square-wave frequency accuracy is not high, frequency and duty cycle narrower issues such as alignment more difficult.
