Abstract – This paper introduces two-channel FIR filter banks synthesized using the frequencyresponse masking approach. The proposed filter banks have a lower computational complexity compared with conventional filter banks, especially when the individual filters have narrow transition bands. One price to pay is a somewhat increased overall delay. A design example is included illustrating the e...

The aim of this paper is to examine whether herd behavior exists or not between di®erent types of Japanese banks. Using data of loans outstanding by types of banks from 1980 to 2000, we investigate statistical causality between loans from di®erent types of banks in Japan. Time-series analysis manifested the causality from city banks to regional banks, from long-term credit banks to city banks, ...

Indian banking industry has transformed in recent years due to the globalization market which has resulted in fierce competition. This new competitive environment has resulted in new challenges for the Indian banks especially for public sector banks to retain their share. The present paper is mainly concerned with the analysis of factors that influence the performance of banks. The paper examin...

This correspondence deals with multiwavelets, which are a recent generalization of wavelets in the context of time-varying filter banks and with their applications to signal processing and especially compression. By their inherent structure, multiwavelets are fit for processing multichannel signals. This is the main issue in which we will be interested here. The outline of the correspondence is...

This correspondence deals with multiwavelets which are a recent generalization of wavelets in the context of time-varying lter banks and with their applications to signal processing and especially compression. By their inherent structure, multiwavelets are t for processing multi-channel signals. This is the main issue we will be interested in here. The outline of the paper is as follow. First, ...

An unrelentingly challenging business environment has also prompted corporate banking clients to take measures to ensure that they have an efficient working-capital ecosystem to support their local treasuries. This trend is also forcing banks to consider new transaction banking models, especially around cost optimization. These circumstances have made e-invoicing an increasingly popular topic o...

In the recent recession and current economic recovery, policymakers have supported housing prices, expecting that improvement in the balance sheets of banks and consumers will spur economic activity. Considering the period of 1988 through 2006, we document that banks which are active in strong housing markets increase mortgage lending and decrease commercial lending. Firms that borrow from thes...

Article history: Received 6 April 2007 Received in revised form 19 September 2008 Accepted 19 September 2008 Available online 11 October 2008 We examine investment banks' networking function in capital markets, using a sample of Private Investments in Public Equity (PIPEs). We argue that investment banks develop relationships with investors through repeat dealings, and that investment banks' ne...

The Symmetric Delay Factorization (SDF) is introduced in 1] for synthesizing linear phase paraunitary lter banks and is applied successfully in 2] for designing Time-Varying Filter Banks (TVFB). This paper describes a minimal and complete generalized symmetric delay factorization valid for a larger class of paraunitary lter banks, and for an arbitrary (even and odd) number of channels. The appr...
