The experiments involved varying the peak deviation and measuring the bit error probability (BEP) at various signal energy per bit to noise power spectral density ratios (E(b)/N(o)).

The purpose of this investigation was to test the theoretical possibility of an investor earning a positive cash return from the activities of the stock market despite effectively holding no position at all in said market. The sample data were the daily returns for the shares of the 780 companies listed on the NASDAQ and the New York Stock Exchange (“NYSE”), which fell within the top 500 listed companies by market capitalisation between 1 January 2005 and 31 December 2017.

Abstract:
A 4 bit, Rom-Less Direct Digital Frequency Synthesizer (DDFS) is designed in 65nm CMOS technology. Interleaving with Return-to-Zero (RTZ) technique is used to increase the output bandwidth and synthesized frequencies. The performance of the designed synthesizer is evaluated using Cadence Virtuoso design tool. With 3.2 GHz sampling frequency, the DDFS achieves the spurious-free dynamic range (SFDR) of 60 dB to 58 dB for synthesized frequencies between 200 MHz to 1.6 GHz. With 6.4 GHz sampling frequency, the synthesizer achieves the SFDR of 46 dB to 40 dB for synthesized frequencies between 400

Abstract:
This research project explores a direction in the formation of sound and image. In the creation of a series of 'moving paintings' I bring together pieces of moving image and sound using techniques derived from musique concr??te. I have coined the term 'moving painting' to describe these sound/image objects that have grown out of an attention to the form, activity, rhythm and texture of sound and image. This project develops from an understanding that sound and image can be constructed on their own terms as opposed to being organised by specific plot devices. This text offers a context for the

Without any pre-amplification on the degraded optical NRZ PRBS data, its extinction ratio is greatly improved from 7.13 dB to 13.6 dB after converting into a RZ PRBS data. Low bit-error-rate (BER) of 10-12 at data rate up to 10 Gbit/s is obtained with a received

In this thesis, a new calibration structure to improve the element mismatch is presented. Besides, the nonlinear transient output also degrades the dynamic performance. Recently, the return-to-zero method is used to attenuate the output when this nonlinear transient occurs, but loses ha
