Offering a practical alternative to the conventional methods used in signal processing applications, this book discloses numerical techniques and explains how to evaluate the frequency-domain attributes of a waveform without resorting to actual transformation through Fourier methods. This book should prove of interest to practitioners in any field who may require the analysis, association, recognition or processing of signals, and undergraduate students of signal processing.

This book is a frank and hopeful meditation on the recurring tragedy of genocide that should be read by anybody who cares about its prevention. Hirsch argues if we are to successfully confront, prevent, or control the most egregious aspects of genocidal violence, we must create containing political institutions and social mechanisms. But ultimately human nature must change to temper the worst excesses of genocidal violence, given its long and intractable historical presence. Hirsch looks hard at complex realities and proposes how to build a politics of prevention. Focusing on the United States, a political movement must be built that supports the politics of prevention in the international realm. Long-term prevention depends on changing how humans view each other, though. Creating a new ethic of life-enhancing behavior based on the ideology of universal human rights that is passed on from generation to generation via the process of political socialization ultimately is our best hope of preventing future genocides.

This book begins with the fact that there is apparently nothing historically unique about human beings killing one another in relatively large numbers. Genocide appears to be a phenomenon that has been a part of human history since we began to record our worst excesses. Certainly it has been in the forefront of human consciousness as the last century came to its bloody conclusion. It is not an intractable problem. A mass movement to prevent genocide can be built, and once created it should pressure the federal government to focus its foreign policy on the prevention of genocide.

More than sixty million people have been victims of genocide in the twentieth century alone, including recent casualties in Bosnia and Rwanda. Herbert Hirsch studies repetitions of large-scale human violence in order to ascertain why people in every historical epoch seem so willing to kill each other. He argues that the primal passions unleashed in the cause of genocide are tied to the manipulation of memory for political purposes.

According to Hirsch, leaders often invoke or create memories of real or fictitious past injustices to motivate their followers to kill for political gain or other reasons. Generations pass on their particular versions of events, which then become history. If we understand how cultural memory is created, Hirsch says, we may then begin to understand how and why episodes of mass murder occur and will be able to act to prevent them. In order to revise the politics of memory, Hirsch proposes essential reforms in both the modern political state and in systems of education.
