A second-order differential highpass filter constructed according to the present invention includes a difference amplifier and a feedback processing circuit. The difference amplifier includes an opera
In more particular, the input video signal is separated through passing a horizontal lowpass filer 451 and a horizontal highpass filter 452 of e.g. QMF mode to two, low and high, horizontal frequency components which are then subsampled to a half of their quantities by two subsamplers 453...
In addition, the design of the loop filter gains becomes difficult since the overall transfer function is of a high order. An enhanced structure SOGI-PLL (ESOGI-PLL) is proposed in [26]. This has a simple design and adequate performance when exposed to high DC offset values. However, the...

Xcell Journal 29 XCELLENCE IN EDUCATION ■ Reusability, in order to avoid unnecessary waste of the hard- ware and the school budget. ■ High performance at an afford- able cost. We had to control a large number of devices and peripherals that were not fully defined, but needed to operate ...
To overcome this, we have designed a sharp cut-off (5 MHz), low-pass, composite filter, which can be inserted between the four-way aperture equalizer and the video display. Suppression ofhigh and !ow video signa!s: Base and/or peak signal clipping can be used to expand differences in ...
Figure 3. Structure diagram of the link of adaptive estimation of back-EMF. 3.3. Calculation of Rotor Velocity and Position Since the link of adaptive estimation of the back-EMF is adopted in the algorithm and the low-pass filter is not used, the problem of the phase delay caused by the...
To address the issue of mechanical resonance frequency detection in dual-inertia servo systems, this paper proposes an online identification method for mechanical resonance frequency using a low-pass filter and cascaded second-order generalized integrator—frequency-locked loop (LPF-CSOGI-FLL). Initially...
-Due to high density of fitting ponit, fidelity of waveform is high and harmonic component is small, which don't have a strict requirement on the low- pass filter. Consequently, it has good characteristics of transient, phase frequency and amplitude frequency, which is easy to perf...
