The fundamental operations of a Finite Impulse Response (FIR) digital filter are multiply and accumulate (MAC). Thus, the complexity of the filter largely depends on the complexity of the multiplier blocks. There exist several techniques to efficiently implement the multiplier using add and shift operations exclusively. Such designs are termed as multiplierless. The Single Constant Multiplication/Multiple...
A two order dual-band bandpass filter using a half-wavelength step impedance resonator to operate at the passbands 2.45 GHz and 5.45 GHz is proposed. Ground slots were embedded below the coupled line section to increase coupling that resulted in passbands of 560 MHz and 470 MHz. Four transmission zeroes obtained at 1.75 GHz, 3.79 GHz, 6.23 GHz and 9.34 GHz, near the two passband edges enhanced the...
of a tunable band pass filter using one dimensional ternary periodic refractive index profile has been presented. Design of the proposed filter is based on the model of Kronig–Penny in solid state physics. In this present filter, the desired wavelength regions can be tuned by altering the temperature or the incidence angle. A Ge/Si/air multilayer system is considered here. The refractive indices of...
