To simulate fractional order low-pass filters, the bias currents of [g.sub.m7] and [g.sub.m8] have to be equal to zero and thereby [B.sub.3] goes to zero and (3) can become realizable.
A relative sensitivity analysis of the presented F-D (1 + [alpha])-order low-pass filter has been carried out.

(2) With the help of two first-order low-pass filters, the derivatives of virtual control inputs are obtained.
The main idea of the adaptive low-pass filter is to set the smoothing factor a dynamically.
Low-pass filters passbands were set to 500 Hz hence the input signal at the frequency 500 Hz passed through these filters without attenuation.
A detailed design procedure starting from the normalized Chebyshev low-pass filter to a final optimized microstrip dual-band bandpass filter is also presented.
Finally, a novel low-pass filter incorporating two improved DSCMRCs connected in series is proposed with an excellent performance of stopband rejection from about 4 GHz up to 25 GHz.
[y.sub.c](n) is the results of v(n) passing dynamic compensation network, and [y.sub.L](n) is the dynamic compensated data after low-pass filter. M(s) represents the transfer function of the force sensor, H(s) represents the transfer function of the dynamic compensation, L(s) represents the transfer function of the low-pass filter, and C(s) represents the transfer function of the whole force sensor system.
Recently, slotted-ground-plane resonators in the low-pass filter have attracted much attention [1-20] because they have numerous advantages like circuitry size reduction and spurious response suppression.
Washington, Oct 21 (ANI): Scientists at Nanyang Technological University (NTU) have designed the world's smallest on-chip low-pass filter which is 1,000 times smaller than existing off-chip filters.
A low-pass filter with a cutoff of 80 Hz to 100 Hz is desirable to remove extraneous noise.
