This paper present a new technique in digital waveform synthesizers based on the use of the first quadrant in order to present the other three quarters. This will reduce the size of the memory locations to the quarter, and increase the number of samples per period four times in comparison with the full wave synthesizer.

A Wideband Frequency Synthesizer for Built-in Self Testing of Analog Integrated Circuits. (August 2004) Wenjian Yan, B.S., Texas A&M University Chair of Advisory Committee: Dr. Jose Silva-Martinez The cost to test chips has risen tremendously. Additionally, the process for testing all functionalities of both analog and digital part is far from simple. One attractive option is moving some or all...

A fully integrated dual-mode frequency synthesizer for GSM and Wideband CDMA (WCDMA) is presented. The synthesizer is designed to maximize hardware sharing between the two modes by applying fractional frequency synthesis to GSM mode and integer frequency synthesis to WCDMA mode. The shared components include phase frequency detector (PFD), charge pump (CP), loop filter, integer frequency divide...

The previously proposed phantom silhouette method is promising for converting ordinary speech into whispered speech. It a simple parametric that uses high-quality vocoder-type analysis and synthesis. An sample first analyzed using the WORLD vocoder. Then, based on extracted spectral envelope, features are manipulated so voice sounds like whisper. target synthesized by driving it with white nois...

A software formant synthesizer isdescribed that can generate synthetic speech using a laboratory digital computer. A flexible synthesizer configuration permits the synthesis of sohorants by either a cascade or parallel connection of digital resonators, but frication spectra must be synthesized by a set of resonators connected in parallel. A control program lets the user specify variable control...

A new approach to video coding is presented, where video scenes are classified into textures with subjectively relevant and irrelevant details. We apply this idea to improve video coding by using a texture analyzer and a texture synthesizer. The analyzer identifies the texture regions with no important subjective details and generates coarse masks as well as side information for the synthesizer...

Chang-Wan Kim et al. 437 A CMOS frequency synthesizer block for multi-band orthogonal frequency division multiplexing ultrawideband systems is proposed. The proposed frequency synthesizer adopts a double-conversion architecture for simplicity and to mitigate spur suppression requirements for out-of-band interferers in 2.4 and 5 GHz bands. Moreover, the frequency synthesizer can consist of the f...

I present FutureBooster, a granular synthesizer for ambient applications. Implemented in the Max/MSP programming language, FutureBooster offers the performer or composer a wide variety of soundscapes and textures. The synthesizer can run as a standalone application or as a VST plug-in and can be controlled using a MIDI keyboard. As well, audio effects such as delay and reverb are available to f...

We introduce a novel laser synthesizer with a simple configuration that contains no phase lock loop. This laser synthesizer generates an optical beat signal by modulating a CW light using a phase modulator and selecting two line spectra from modulation sidebands using serially-connected fiber Bragg gratings. With this configuration, the optical beat signal is obtained from a single laser source...
