The filter is realized for converting an active distributed RC to a transistor-only high pass filter circuit. The frequency response of high-pass was examined by a MOSFET model. Preliminary experimental simulation results by PSpice programs for high frequency high-pass filter is presentedPirajnanchai...
The invention discloses a device for compensating frequency response characteristic of a high-pass filter and a method thereof as well as a zero-if receiver; wherein the device for compensating frequency response characteristic of the high-pass filter consists of an A/D conversion module ...
Design a fifth-order analog lowpass Bessel filter with approximately constant group delay up to104rad/second. Plot the magnitude and phase responses of the filter usingfreqs. wc = 10000; [b,a] = besself(5,wc); freqs(b,a) Compute the group delay response of the filter as the negative ...
Less familiar, though, is the flat response that is now more commonly exhibited by modern, high- bandwidth digital oscilloscopes. A digital oscilloscope has a shorter chain of analog amplifiers, and it can use digital signal processing techniques to optimize the response for accuracy. More important...

One thing I noticed is that in your plot of the frequency response, there is a jump from 50 Hz to a little over 100 Hz where the response is not smooth. Neither the PGA nor the digital filter could be responsible for such a transition. Is it ...
Before the AD converter I have to remove the DC component. For that I use an active high pass filter. The cutoff frequency of the filter is <1Hz. I have a problem of wave on the output of the filter. Because the values of the capacitor and of the resistor are quiet high (1uF ...
To improve the transient response, a virtual inductor with high-pass filter in synchronous d-q frame is proposed. The effectiveness of the virtual inductor is explained by the frequency response of the inverter. Finally, experimental results are given to verify the effectiveness of the scheme. ...
motor,to avoid demodulation failure of the HF response signal for extraction of rotor position information and torque ripple due to improper selection of the amplitude of injection signal,this paper presents a method for importing the high-pass resonator filter into the motor position extraction ...
