mixed high frequency signal 中文意思是什麼
mixed high frequency signal
解釋
高頻混合信號-
Continuous - time analog filter is the only method when processing high frequency signal ( usually above 1mhz ) in low power consumption. it has been widely used in the area of communication, electronic measurement, instruments, autocontrol, etc. it ’ s especially used in digital and analog mixed signal processing and communication integrated circuit. current - mode filter becomes the new research direction in the world, as it ’ s high speed, low power consumption and simple configuration
提出了基於ota的多功能電流模式雙二階濾波器,基於ota的八階切比雪夫濾波器,用模擬lc梯形電路法設計橢圓低通濾波器時,在傳統的狀態變量選取方法的基礎上,用改進后的狀態變量選取方法得到了( k + 1 )階橢圓函數低通濾波器的簡化信號流圖,實現了簡化的基於ota的橢圓低通濾波器電路。 -
The mixed control chip sg3525a combined with hardware pi controller generates the high - frequency pwm pulse for the first inverter. the digital control block tms320lf2407a mainly provides current preset for constant - current source through the outer filter, pwm pulse for the second inverter and drive signal for the high - frequency pulse power supply
其中變極性電源的一次逆變pwm信號由pwm發生晶元sg3525a ,配以外部硬體電路pi調節器產生;一次逆變閉環控制迴路的電流給定(配以外部濾波) 、二次逆變pwm驅動以及高頻脈沖電源的控制則由tms320lf2407a數字控制器實現。
