A perfect interpolation of discrete Fourier transform

1993 IEEE International Symposium on Circuits and Systems (2003)

H. Babić Sven Lončarić

The authors consider conditions and a solution for a perfect interpolation of the discrete Fourier transform (DFT) spectrum. Free variables in the problem are chosen to enable the shortest sequence length. Some sequences for an efficient implementation in cascade interpolation structures are computed, and the required number of multiplications for the procedure is determined.< >

Efficient implementation of sharpened CIC decimation filters for software radio receivers

G. Rajic H. Babić

We propose an efficient structure for sharpened, cascaded integrator comb (CIC) based, decimation filter. Novelty of proposed structure is that it can be achieved for any decimation factor and its efficient finite impulse response (FIR) implementation form. It consists of multirate cascade of sharpened CIC filters with lower (prime) decimation factors. Every cascade stage can be implemented in nonrecursive FIR form with sharpened higher order Comb filters as building blocks. Applying polyphase decomposition, every stage can work on lower decimation rate depending of decimation factor of that stage. Additionally, due to special pole structure of filter stages in cascade, first few stages can be implemented with reduction in system order, depending of stage position and decimation ratio.

System functions with minimum time-bandwidth product based on the higher order moments

H. Babić Mladen Vučić

Systems of finite order with minimum time-bandwidth products are considered. The time and frequency response spreads are defined by moments of the higher order in both domains. Minimizing the product of the moments, causal systems with the largest energy concentration in the time and frequency domain are obtained. The optimization is carried out for transfer functions up to the eighth order with two and four complex zeros. The moment orders are chosen from two to eight. The influence of the zeros and the moment order on system properties are considered. The complete data suitable for filter design are given.

Effect of zeros on IIR filters with symmetric impulse response

European Signal Processing Conference (2000)

Mladen Vučić H. Babić

The properties of the symmetric impulse response filters with real and complex zeros are considered. The pole-zero locations of the rational transfer functions are found, by minimization of the symmetry error. The contribution of zeros to the symmetry error is shown and compared to the systems with all zeros at the origin. The design procedure of such filters based on time or frequency domain requirements is outlined.

Systems with minimum time-bandwidth product based on the higher order moments

IEEE International Conference on Signal and Image Processing (2000)

H. Babić Mladen Vučić

Time functions whose duration and bandwidth are as small as possible have practical as well as theoretical interest. Many criteria are employed for calculation of such time functions. Moments of the impulse response and moments of the frequency response can be used for characterization of response time and frequency band. The second moments were used for the definition of the uncertainty principle. In this paper response functions of finite order systems are characterized not only by the second but also with fourth, sixth and eight moments. To find out properties of obtained functions and values of time frequency band products, a numerical optimization is carried out for all-pole transfer functions, up to the eight orders. Properties of obtained systems are given and compared.
