As is well known, there are two kinds of constant delay allpole lowpass digital filter functions: maximally flat type and equiripple type. In some cases of waveform transmission, transfer functions with inter mediate characteristics between the two forementioned types are preferable. This paper ...

The main disparity between LPF-low pass filter and high pass filter-HPF is the frequency range which they exceed. AnHPF (high pass filter)is one kind of circuit which permits the high frequency and blocks low frequency for flowing through it. In the same way, anLPF (low pass filter)is ...
There is a double R-C network (marked in a red square) present in the circuit hence the filter is a second-order low pass filter. ‘RL’ is the load resistance connected at the op-amp output. Second Order Low Pass Butterworth Filter Derivation ...
Hence, it appears that a low-pass filter could easily address this issue. However, it is noted that these so-called high-frequency interferences only appear in the high-frequency domain when the pile dimension (radius) is small or the shear wave velocity of the pile material is high. As ...
A Low-Reference Spur MDLL-Based Clock Multiplier and Derivation of Discrete-Time Noise Transfer Function for Phase Noise Analysis 来自 Semantic Scholar 喜欢 0 阅读量: 58 作者:GY Tak,K Lee 摘要: A multiplying delay-locked loop (MDLL)-based clock multiplier with a two-step phase aligning ...
The proposed structures employ properties of both a variable bandwidth (VBW) filter and a variable equalizer (VE) with variable coefficients. The overall transfer function of the proposed reconfigurable lowpass equalizer (RLPE) is a weighted linear combination of fixed subfilters where the weights ...
In an embodiment of the invention, there is provided a low pass filter circuit comprising: an amplifier having a single-ended output; a first line and a second line, the first line and the second line being arranged to receive a differential signal; a first switch for selectively connecting ...
