Any system consisting of a sequence of multiplicative filters inserted between several fractional Fourier transform stages, is equivalent to a system composed of an appropriately chosen sequence of multiplicative filters inserted between appropriately scaled ordinary Fourier transform stages. Thus every operation that can be accomplished by repeated filtering in fractional Fourier domains can a...

The realization of the second-order universal (low-pass, band-pass, high-pass, band-reject, and all-pass) active current filter using a single second-generation current controlled conveyor (CCCII), two grounded capacitors, and one resistor is proposed in this paper. Three input signals and the bias current of the active element determine the filtering type of the output signals. H-Spice simulat...

Effects of low-pass filtering on the judgment of vocal affect in speech directed to infants, adults and foreigners. ACCEPTED MANUSCRIPT 2 ABSTRACT Low-pass filtering has been used in emotional research to remove the semantic content from speech on the assumption that the relevant acoustic cues for vocal affect

Noise Filtering in audio signals has always been a challenge since the noise is spread across a large bandwidth and overlaps the spectral range of the audio signal being recovered. In audio systems all these can be kept below the audible level but ambient noise may not be avoided even if the audio system is designed according to the best practices. So, there have been several audio filtering te...

This paper is concerned with the full-order H∞ filtering problem for uncertain differential linear repetitive processes (LRPs). uncertain differential linear repetitive process (LRP) assumed to be stable along the pass, our attention is focused on the design of a full-order filter, which guarantees the filtering error process to be stable along the pass, and minimizes an upper bound for theH∞ n...

In this paper, we proposed a method to reduce quantization error. In order to reduce quantization error, low pass filtering is applied on neighboring samples of current block in H.264/AVC. However, it has a weak point that low pass filtering is performed regardless of prediction direction. Since it doesn’t consider prediction direction, it may not reduce quantization error effectively. Proposed...
