Negative-peak detector负峰值检知器电路: R1= 1 M, C1= 10 uF 只有在I/P电位低于OP-端电位时, O/P电位继续降低.负峰值必须高于电源负值，所得数据为最高值。......
Positive-peak detector正峰值检知器电路: R1 = 1 K, R2 = 1 M, C1 = 10 uF只有在I/P电位高于OP-端电位时, 才能使Q1导通, O/P电位继续升高.正峰值必须低于电源正......

Opamps are very useful. But one of their major drawbacks is the requirement of a dual supply. This seriously l......
