Secondly, converting the RGB image to CIE L*a*b* and apply
band-pass filters,
Band-pass filtering can be used to enhance edges (suppressing low frequencies).
Using (1), the filter design parameters [k.sub.1], [k.sub.2], [k.sub.3], [k.sub.4], and [k.sub.5] for the five regions of the
band-pass filter are evaluated and listed as follows:
Keywords: Dual-band filters, frequency transformation, real frequency technique,
band-pass prototype.
The RLF can be used in a standalone environment, but is an excellent companion to CTS's Clearplex
band-pass filter and duplexer products.
By replacing the metal reflection plate with a
band-pass FSS, an AFSS can be designed.
After the first stage LNA, a microstrip coupled line
band-pass filter is implemented.
Its implementation is based on such classical 2nd-order frequency filter structure, which provides at least
band-pass and low-pass responses as it is depicted in Fig.
Customers can also choose the optical filters such as IR-pass filters, IR
band-pass filters, NIR notch filters etc.
In this paper, before presenting new models of coupled transmission lines it is necessary to present and analyze the general method of designing
band-pass filters.
The manufacturing techniques for third-order
band-pass filter based on SIW are given.
