This short note is a description of the analysis of single phase induction motors. It is intended to be read along with a description of the analysis of polyphase motors1.This will be called the ’reference document’. The style of analysis used here is described in more detail in that note and many of the elements of this analysis appear only in that other note. The single phase machine contempl...

A set consisting of K subsets M sequences length L is called a complementary sequence expressed by A(L, K, M), if the sum out-of-phase aperiodic autocorrelation functions within subset and cross-correlation between corresponding in any two are zero at phase shift. Suehiro et al. first proposed A(Nn, N, N) where N n positive integers greater than or equal to 2. Recently, several sets related Sue...

Analog-to-digital converters based on sigma-delta modulation have shown promising performance, with steadily increasing bandwidth. However, associated with the increasing bandwidth is an increasing modulator sampling rate, which becomes costly to decimate in the digital domain. Several architectures exist for the digital decimation filter, and among the more common and efficient are polyphase d...

In this paper, we present a new method for the design and implementation of modulated filter banks with perfect reconstruction. It is based on the decomposition of the analysis and synthesis polyphase matrices into a product of two different types of simple matrices, replacing the polyphase filtering part in a modulated filter bank. Special consideration is given to cosine-modulated as well as ...

Binary tree-structured filter banks have been employed in the past to generate wavelet bases. While the relation between paraunitary filter banks and orthonormal bases is known to some extent, there are some extensions which are either not known, or not published so far. In particular it is known that a binary tree-structured filter bank with the same paraunitary polyphase matrix on all levels ...

It is widely believed that the walsh code is the best to provide covering for a CDMA channel due to its orthogonality. However, it exhibits a severe aperiodic ACF and variation of its aperiodic ACF pattern for each code. Hence, the comparison of MAI performances of walsh sequences with other three orthogonal sequences as a channel cover code in DS-CDMA was established. The aperiodic ACF and CCF...

An analysis of the local convergence speed of constant gain algorithms for direct form IIR adaptive ̄lters is initially presented, showing the adverse e®ects that result from the proximity of the poles of the modelled system to the unit circle and, for complex poles, to the real axis. A global analysis of the reduced error surface in these cases is also presented, which shows that, away from th...

----Pulse Shaping Filters or Root Raised Cosine (RRC) low pass filters emerges as one of the hottest topic in field of Wireless Communication technology. Low pass filters are used for decimation and for interpolation. When decimating, low pass filters are used to reduce the bandwidth of a signal prior to reducing the sampling rate. This is done to minimize aliasing due to the reduction in the s...
