The focus of Spectrum is the range of contemporary ideas that runs from conservative to liberal to radical conceptions of state and society, rarely considered in the same optic. It looks at the theories of major minds of the twentieth-century Right, including Carl Schmitt, Leo Strauss and Friedrich von Hayek; liberal philosophers such as John Rawls, Jurgen Habermas and Norberto Bobbio; and significant figures in the culture of the Left: the historians Edward Thompson, Robert Brenner and Eric Hobsbawm; the classicist Sebastiano Timpanaro; the sociologist Goran Therborn; the novelist Gabriel Garcia Marquez. The book concludes with some comparative observations on the two leading intellectual periodicals of the UK and USA, the London Review of Books and New York Review of Books; and a piece of family history.

This lecture covers the fundamentals of spread spectrum modulation, which can be defined as any modulation technique that requires a transmission bandwidth much greater than the modulating signal bandwidth, independently of the bandwidth of the modulating signal. After reviewing basic digital modulation techniques, the principal forms of spread spectrum modulation are described. One of the most important components of a spread spectrum system is the spreading code, and several types and their characteristics are described. The most essential operation required at the receiver in a spread spectrum system is the code synchronization, which is usually broken down into the operations of acquisition and tracking. Means for performing these operations are discussed next. Finally, the performance of spread spectrum systems is of fundamental interest and the effect of jamming is considered, both without and with the use of forward error correction coding. The presentation ends with consideration of spread spectrum systems in the presence of other users.
