variable gain

• 可变放大,可变增益

variable gain的用法和样例：

例句

1. To gain further bisymmetric baseband signals, the proposed transconductance stage is formed with a cross-coupled type.
   之后经过可变增益放大器将升频后之讯号放大到功率放大器所要求之强度。
2. A low power mixer and a basedband variable gain amplifier are designed for frequency downconversion and gain-adjustment, respectively.
   最后实现了一个低功率的混频器及基频可变增益放大器，且此放大器可线性调整增益。
