Digital signal processing (DSP) refers to anything that can be done to a signal using code on a computer or DSP chip. To reduce certain sinusoidal frequency components in a signal in amplitude, digital filtering is done. One may want to obtain the integral of a signal. If the signal comes from a tachometer, the integral gives the position. If the signal is noisy, then filtering the signal to reduce the amplitudes of the noise frequencies improves signal quality. For example, noise may occur from wind or rain at an outdoor music presentation. Filtering out sinusoidal components of the signal that occur at frequencies that cannot be produced by the music itself results in recording the music with little wind and rain noise. Sometimes the signal is corrupted not by noise, but by other signal frequencies that are of no present interest. If the signal is an electronic measurement of a brain wave obtained by using probes applied externally to the head, other electronic signals are picked up by the probes, but the physician may be interested only in signals occurring at a particular frequency. By using digital filtering, the signals of interest only can be presented to the physician.

The political situation in Ireland at the beginning of the 20th century was characterised by crisis and change. Armed rebellion against the British Crown, the prosecution of the Anglo-Irish War, the emergence of the Irish Free State, and the eruption of the Civil War over the treaty with Great Britain ensured that the birth of the modern Irish nation was bloody and difficult. This book details the life of an average Volunteer, and includes the experiences of internment, the lack of established medical facilities for wounded, life on the run, discipline, and typical duties.

The world's most revered and eloquent interpreter of evolutionary ideas offers here a work of explanatory force unprecedented in our time--a landmark publication, both for its historical sweep and for its scientific vision. With characteristic attention to detail, Stephen Jay Gould first describes the content and discusses the history and origins of the three core commitments of classical Darwinism: that natural selection works on organisms, not genes or species; that it is almost exclusively the mechanism of adaptive evolutionary change; and that these changes are incremental, not drastic. Next, he examines the three critiques that currently challenge this classic Darwinian edifice: that selection operates on multiple levels, from the gene to the group; that evolution proceeds by a variety of mechanisms, not just natural selection; and that causes operating at broader scales, including catastrophes, have figured prominently in the course of evolution.

It is well recognised that company law is a large and complex subject which has expanded rapidly in volume in recent years. Added to this is the continual reform to the existing law. This is partly due to the need to comply with obligations imposed on the United Kingdom from Brussels, but partly because of the increasing complexity of commercial life generally. There is no sign that the growth and reform is at an end. In addition, there are now two established series of specialist company law reports (Butterworths Company Law Cases and British Company Cases) which have obviously resulted in many more cases reaching the public domain for comment and analysis. Further, no work on Company Law can now ignore the extra-legal controls and influences on director’s conduct contained in the recent reports on corporate governance nor the proposals for reform put forward, in particular, by the Law Commission. This edition deals with the main features of both the Law Commission’s Report on Shareholder Remedies and the Law Commission’s Consultation Paper on the reform of director’s duties.

Jurgen Habermas is unquestionably one of the foremost philosophers writing today. His notions of communicative action and rationality have exerted a profound influence within philosophy and the social sciences. This volume examines the historical and intellectual contexts out of which Habermas' work emerged, and offers an overview of his main ideas, including those in his most recent publication. Amongst the topics discussed are his relationship to the Frankfurt School of critical theory and Marx, his unique contributions to the philosophy of the social sciences, the concept of 'communicative ethics', and the critique of post-modernism. New readers and non-specialists will find this the most convenient, accessible guide to Habermas currently available. Advanced students will find a conspectus of recent developments in the interpretation of Habermas.
