Sine-wave and Trigger Pulse Generator for SS-OCT

A Novel Sine Wave Based UWB Pulse Generator Design for Single/Multi-User Systems

In this study, a novel Ultra Wideband (UWB) pulse generator design for singleand multi-user systems is presented. The proposed pulse generator is based on new simple and effective design to generate the UWB pulses through sine wave shaping. For single-user systems, three models for the proposed pulse generator working with Frequency Modulation (FM), Bi-Phase Modulation (BPM) and On-Off Keying (...

Hardware Implementation of Sine Wave Generator using CORDIC Algorithm

This paper describes a hardware realization of Sine wave generator using CORDIC algorithm. A complex oscillator based on the unfolded CORDIC algorithm has been implemented, which produces periodic sine and cosine samples for any specified angle increment. Where the frequency accuracy is achieved by residual angle correction unit and stability is achieved using AGC unit, also phase jitter is avo...

FPGA Implementation of Pipelined CORDIC Sine Cosine Digital Wave Generator

The coordinate rotation digital computer (CORDIC) algorithm is well known iterative algorithm for performing rotations in digital signal processing applications. Hardware implementation of CORDIC results increase in Critical path delay. Pipelined architecture is used in CORDIC to increase the clock speed and to reduce the Critical path delay. In this paper a hardware efficient Digital sine and ...

Pulse Wave Analysis and Pulse Wave Velocity

momanometer that provides arterial pressures (brachial systolic and diastolic pressure) is coming under question. The concerns extend well beyond the familiar issue of “white coat” hypertension, home and 24-h blood pressure recordings, and the phase-out of mercury based instruments. These concerns relate to the inaccuracy of all cuff devices for measuring pressure within the brachial artery, th...
