In this paper we present a novel sound source separation algorithm which requires no prior knowledge, no learning, assisted or otherwise, and performs the task of separation based purely on azimuth discrimination within the stereo field. The algorithm exploits the use of the pan pot as a means to achieve image localisation within stereophonic recordings. As such, only an interaural intensity di...

In this paper two types of current control techniques, namely, direct and indirect current control techniques are employed to a three phase shunt active power filter for the compensation of the harmonics in the current caused by the non-linear loads. The difference between these two types of current control technique is in the number of current sensors used. In direct current control technique ...

A compact and low-power design of a 12-bit binary-weighted current-steering DAC is presented. Instead of 4096 unit current cells, the proposed design uses 192 unit current sources with two reference currents. The silicon area of the generation circuit of two reference currents is very compact as well. The area of the total current source arrays is smaller than four times the area of 6-bit curre...

This paper presents a self-tuning filter (STF)-based adaptive linear neuron (ADALINE) reference current generation algorithm to enhance the operation of a three-phase three-level neutral-point diode clamped (NPC) inverter-based shunt active power filter (SAPF) under non-ideal (unbalanced and/or distorted) source voltage conditions. SAPF is an effective and versatile mitigation tool for current ...

Power quality standards (IEEE-519) require to limit the total harmonic distortion within satisfactory range caused by power electronic based devices. Our work deals with the design of hybrid active filter to reduce current perturbations produced by power electronics based devices. The Instantaneous Active and Reactive Power Method (pq) is used to perform the identification of disturbing current...

This paper describes the study of a simple two-branch current reference where the sum of branch currents (that is, the total current) is compensated with temperature. This approach is the most adequate when the reference must supply current in a charge with grounded or connected to voltage-supply end. The second-order thermal compensation of the reference current is analyzed here. The equation ...

Reference spurs are one of the main problems in integer-N phaselocked loops (PLLs). A ratioed current charge pump is proposed to suppress reference spur magnitude in the PLL output. The ratioed current charge pump can be implemented by resizing the source and drain network of the charge pump. A formula to calculate the ratioed current and transistor size is presented. The reference spur magnitu...
