We have shown that bandfolding in the DCT domain does not result in a downsampling of the signal. The result is two convolution operations that involve both the odd and even samples of the signal. The impulse response of the resulting filters (h 1. It H. Ir 1). h i,') depends on the parity of the samples and on the subband (low or high). ACKNOWLEDGMENT The… (More)
Discrete wavelet coefficients of input and output of a Linear Time Invariant system, respectively, are shown to be related by a transformation matrix whose elements depend upon characteristics of the system and choice of wavelet bases. A filter bank implementation of the matrix using digital filters, Up-and Down-samplers is also given.
Testing and fault-diagnosis of core-based systems are both difficult problems. Being able to identify which module in the core-based system is faulty has become very important. In this paper, we present algorithms to introduce test points for improving the di-agnosability of a digital system. We define a measure of diagnosability known as module resolution… (More)
