电源频率恒定条件下在时间领域内对电路进行分析称为时课件.ppt

电源频率恒定条件下，在时间领域内对电路进行分析,称为时域分析。;滤波电路主要有： 低通滤波器、高通滤波器、带通滤波器等。;(2) 传递函数（转移函数）;频率特性;频率特性曲线;通频带： 把 0 ? ??0的频率范围称为低通滤波电路的通频带。?0称为截止频率。 (半功率点或3分贝点);2. RC高通滤波电路;(3) 频率特性曲线;3. RC带通滤波电路;幅频特性： ;(3) 频率特性曲线;由频率特性可知;在同时含有L 和C 的交流电路中，如果总电压和总电流同相，称电路处于谐振状态。此时电路与电源之间不再有能量的交换，电路呈电阻性。;同相;电路发生谐振的方法：;(4) 电压关系;令：;注意;4. 谐振曲线;(2) 电流的谐振曲线;通频带：;5.串联谐振应用举例;例1：;例1：;二、 并联谐振;(2) 并联谐振的特点;?1;例2：;例3：;又：;l7%OAm8PBn9QCoa*RDpa(SEqb)TFqc-UGrd+VGse0WHtf1WIug2XJvh2YKwi3ZLxi4#Myj5!Nyk6$Ozl7%OAm8PBn9QCoa*RDpa(SEqb)TFqc-UGrd+VGse0WHtf1WIug2XJvh2YKwi3ZLxi4#Myj5!Nyk6$Ozl7%OAm8PBn9QCoa*RDpa(SEqb)TFqc-UGrd+VHse0WHtf1XIug2XJvh3YKwi3ZLxj4#Myj5!Nzk6$Ozl7%PAm8PBn9*QCoa*RDpb(SEqb)TFrc-UGrd+VHse0WHtf1XIug2XJvh3YKwi3ZLxj4#Myj5!Nzk6$Ozl7%PAm8PBn9*QCoa*RDpb(SEqb)TFrc-UGrd+VHse0WHtf1XIug2XJvh3YKwi3ZLxj4#Myj5!Nzk6$Ozl7%PAm8PBn9*QCoa*RDpb(SEqc)TFrc-UGsd+VHse0WItf1XIug2YJvh3YKwi4ZLxj4#Myk5!Nzk6$OAl7%PAm8QBn9*QCoa(RDpb(SEqc)TFrc-UGsd+VHse0WItf1XIug2YJvh3YKwi4ZLxj4#Myk5!Nzk6$OAl7%PAm8QBn9*QCoa(RDpb(SEqc)TFrc-UGsd+VHse0WItf1XIug2YJvh3YKwi4ZLxj4#Myk5!Nzk6$OAl7%PAm8QBn9*RCoa(RDpb)SEqc)TFrd-UGsd+VHte0WEqc-UFrd+UGse0VHtf0WIug1XJvg2YKwh3ZLwi4#Mxj5!Myk6$Nzl7$OAm8%PBn8QCo9*RDoa(SEpb)TEqc-UFrd+UGse0VHtf0WIug1XJvg2YKwh3ZLwi4#Mxj5!Myk6$Nzl7$OAm8%PBn8QCo9*RDoa(SEpb)TEqc-UFrd+UGse0VHtf0WIug1XJvh2YKwh3ZLxi4#Mxj5!Nyk6$Nzl7%OAm8%PBn9QCo9*RDpa(SEpb)TFqc-UFrd+VGse0VHtf1WIug1XJvh2YKwh3ZLxi4#Mxj5!Nyk6$Nzl7%OAm8%PBn9QCo9*RDpa(SEpb)TFqc-UFrd+VGse0VHtf1WIug1XJvh2YKwh3ZLxi4#Mxj5!Nyk6$Nzl7%OAm8%PBn9QCo9*RDpa(SEpb)TFqc-UFrd+VGse0WHtf1WIug2XJvh2YKwi3ZLxi4#Myj5!Nyk6$Ozl7%OAm8PBn9QCoa*RDpa(SEqb)TFqc-UGrd+VGse0WHtf1WIug2XJvh2YKwi3ZLxi4#Myj5!Nyk6$Ozl7%OAm8PBn9QCoa*RDpa(SEqb)TFqc-UGrd+VGse0WHtf1WIug2XJvh2YKwi3ZLxi4#Myj5!Nyk6$Ozl7%OAm8PBn9QCoa*RDpa(SEqb)TFqc-UGrd+VHse0WHtf1XIug2XJvh3YKwi3ZLxj4#Myj5!Nzk6$Ozl7%PAm8PBn9*QCoa*RDpb(SEqb)TFrc-UGrd+VHse0WHtf1XIug2XJvh3YKwi3ZLxj4#Myj5!Nzk6$Ozl7%PAm8PBn9*QCoa*RDpb(SEqb)TFrc-UGrd+VHse0WHtf1XIug2XJvh3YKwi3ZLxj4#Myj5!Nzk6$Ozl7%PAm8PBn9*QCoa*RDpb(SEqc)TFrc-UGsd+VHse0WItf1XIug2YJvh3YKwi4ZLxj4#Myk5!Nzk6$OAl7%PAm8
