“…No (after convert from new seq) Using fdatools (Matlab software) to import filter from workspace to the numerator and denominator to enter that particular value at Pole Zero Editor. As a theory, when the z-plane of the zeros lies in the two balancing circle, the envelope of the pulse train tends to be relatively symmetrical in the mid-pulse [12]. All possible positions of the roots in the Z-domain are generated and each position which the radius circle lies has been optimized.…”

Development of technique for synthesizing multilevel sequences with good correlation properties is very useful for several radar applications where as a set of phase and amplitude coded sequences will be synthesized directly for compression technique. In reality, the signal processing also been significant to transmit or store signals, to enhance desired signal component and to extract useful information carried by signals. Consequently, this paper describes affectively methods to generating the finite length multilevel sequence of any length that have low side lobe energy (SLE) and improved energy ratio (ER) in their autocorrelation function (ACF). Testing for the stability and the analyzing of systems zero pattern using z-transform for the generating sequence indicates a possible position of roots in the radius of circle lies. This is illustrated by application of 13-element Huffman code as a starting sequence, this technique more low complexity and compatible compared inverse filtering technique.
