In HMM-based speech synthesis, trained statistical models (context-dependent HMMs) are used to predict duration and generate parameters like mel-cepstral coefficients, log F0 values, and bandpass voicing strengths using the maximum likelihood parameter generation algorithm including global variance (Toda et al, 2007). In the later stages, F0 parameters, bandpass voicing strengths, and the five ...

This paper proposes parallel-coupled stepped impedance resonators (SIRs) used for wideband bandpass filters with reduced size and improved spurious response suppression in out-of-band. The filter design concept is demonstrated by both twoand four-parallel coupled line resonator structures with the same fundamental frequency (f0) of 6.5GHz. The first bandpass filter has been designed using two r...

We discuss a near-infrared (NIR) narrow-band tunable birefringent filter system newly developed by the Big Bear Solar Observatory (BBSO). This is one of the first narrow-bandpass NIR filter systems working at 1.56 μm which is used for the observation of the deepest solar photosphere. Four stages of calcite were used to obtain a bandpass of 2.5 Å along with a free spectral range (FSR) of 40 Å. S...

Dept. of Electrical Engineering, Indian Institute of Technology, New Delhi [email protected] Computer aided design of inductive iris filter in waveguide technology is described here using Mode Matching Method(MMM). Direct coupled cavity niters form compact structures. Such a bandpass filter is first designed using equivalent network theory approach. Mode matching method has been used to a...

This paper aims to present fingerprint image enhancement by using directional circular raised cosine filters which are implemented using a radial component and an angular component. It has been compared with the common filters used for bandpass filtering, i.e. circular Gabor filters and Log-Gabor filters at the same bandwidth. The experimental results have found that the circular raised cosine ...

This paper describes the design and analysis of planar dual-band bandpass filters using stepped impedance resonators. In the proposed filter configurations, dual-band bandpass filters are designed, and realized by using inverted stepped impedance (SIR) resonators. The conventional half wavelength open circuited stub single frequency resonators are replaced with dual band simple two section step...
