C6=270pF时,f=1/T=1000000/30.5280=32756.8H
C6=470uF时,f=1/T=1000000/30.5921=32688.2HZ
C6=670uF时,f=1/T=1000000/30.4744=32814.4HZ
(3)、C4=0.01时:
当C6=270uF时,f=1/T=1000000/2.0561=486357.7HZ
当C6=470uF时,f=1/T=1000000/2.3760=420875.4HZ
当C6=670uF时,f=1/T=1000000/2.6784=373357.2HZ
2、将C4的值恢复为0.033μF,分别调节Rp 在最大到最小之间变
化时的频率和波形如下:
Rp(KΩ) 50 40 30 20 10 0 529553.3 F(HZ) 403746.8 416666.7 420875.4 425170.1 422582.8 (1)、当Rp=50k时,f=1/T=1000000/2.4768=403746.8HZ
(2)、当Rp=40k时,f=1/T=1000000/2.4000=416666.7HZ
(3)、当Rp=30k时,f=1/T=1000000/2.3760=420875.4HZ
(4)、当Rp=20k时,f=1/T=1000000/2.3520=425170.1HZ
(5)、当Rp=10k时,f=1/T=1000000/2.3664=422582.8HZ
