LC二阶低通滤波网络的模拟信号数字化分析
Ideally, the LC filter value is selected for a critically damped, flat passband, and phase response. Two considerations when selecting components for the second-order low-pass filter is the cut- off frequency and Q factor or damping ratio. Figure 6. Effect of Q on Frequency Response TI ...
TI recommends you use a 2nd-order Butterworth Low-Pass filter, because of its flat pass-band and phase response. The Butterworth filter can be designed by using Equation 4 and Equation 5 to determine LC values. C+ wo 1 RL Ǹ2 (4) L + RL wo Ǹ2 (5) 4 Class-D LC Filter ...
That equation is for the resonant frequency, not the -3 dB cutoff frequency. Even DigiKey gets it wrong. https://www.digikey.com/en/resource...sion-calculator-low-pass-and-high-pass-filter Attachments Slide1.PNG 83.4 KBViews: 0 Slide2.PNG ...

we can take the Q factor of X with R_S or R_L. A lowpass filter has a Q factor associated with each section, defined in this way; the Qs are designed so that the peak of one section just fills in the valley of the last, and so on, to get an overall response that is much...
The TLC320AC01 derives the sampling frequency and the bandwidth of its internal low pass filter from the master clock. To enable a sampling rate of exactly 8kHz and the typical filter specification for telecom applications it is necessary to provide 10.368 MHz as MCLK frequency. The low ...
the match of the capacitors and inductors is realized strictly according to equation parameters, and the filter is advantaged by many mechanical and electrical performances such as micro packaging, ultra-large bandwidth, low insertion loss, high rectangular degree, and high stop-band suppression etc....
The filter performance is designed for a wide range of noise frequencies. This low-pass filter starts to attenuate noise at approximately 10 kHz. If a specific frequency noise component is known, such as switching power supplies frequencies, it is recommended that component values be adjusted and...
