乙类互补功放电路如图，若VCC=15V，负载RL=8Ω，T1、T2的VCES均可忽略，若输入信号足够大，则PV的值为（ ）。http://image.zhihuishu.com/zhs/onlineexam/ueditor/201809/fe0d2f6f4a864026a8385ec9f79220cc.png
举一反三
- 如图所示的功率放大电路，若忽略三极管的饱和压降VCES，电源电压为VCC=12V，负载电阻RL=8Ω，则三极管的极限参数V(BR)CEO应满足（）http://image.zhihuishu.com/zhs/onlineexam/ueditor/201809/949cf20edb3149039098f27f2700b11a.png
- 已知f1(t)和f2(t)波形如下，若f(t)=f1(t)*f2(t)，则f(0)=http://image.zhihuishu.com/zhs/onlineexam/ueditor/201906/e38151c6fa664a008f547dd1af821f92.bmp
- 电路如图所示，管子在输入信号vi作用下，在一周期内T1和T2轮流导电约180度，电源电压VCC=20V，负载RL=8Ω，在输入信号Vi=10V（有效值）时，电路的直流电源供给的效率为（）http://image.zhihuishu.com/zhs/onlineexam/ueditor/201809/b96ba06b8c8a43288ea323cb73bf3ab9.png
- 信号f1(t)和f2(t)如下图所示，f(t)=f1(t)*f2(t)，则f(-1)等于http://image.zhihuishu.com/zhs/onlineexam/ueditor/201906/0749958f4da44655959aea343dbe4d9c.bmp
- 已知f(t)↔F(w)，则下列说法正确的是（） A: tf(t)↔wF(w) B: F(t)↔f(w) C: <img src="http://image.zhihuishu.com/zhs/onlineexam/ueditor/201812/e987a05c70d3455bad2fbdef6ce1fc1d.png" /> D: <img src="http://image.zhihuishu.com/zhs/onlineexam/ueditor/201812/92f68075a5ff43708660199e4eed9415.png" />
