Only LTI filters can be subjected to frequency-domain analysis as illustrated in the preceding chapters. After studying this chapter, you should be able to classify any filter as linear or nonlinear, and time-invariant or time-varying.

The great majority of audio filters are LTI, for several reasons: First, no new spectral components are introduced by LTI filters. Time-varying filters, on the other hand, can generate audible sideband images of the frequencies present in the input signal (when the filter changes at audio rates).

Online loans is not overly restrictive, however, because the static analysis holds very well for filters that change slowly with time. For discrete time (digital) systems, the impulse is a 1 followed by zeros. In continuous time, the impulse is a narrow, unit-area pulse (ideally infinitely narrow).

The harmonic components generated by the nonlinearity are often called distortion products. Summing the power of all distortion products and dividing by the power of the sinusoidal component at the fundamental frequency (the only non-distortion component) yields the total harmonic distortion (THD). The THD of a device is usually expressed in decibels (dB).

In general, the output signal contains many new sinusoidal components at frequencies obtained by adding and subtracting the frequencies present in the input signal. In the simplest case of two input frequencies f1 and f2. A truly linear filter does not cause fundamental frequency given by the inverse of the period.

If the period is in units of seconds, then the fundamental frequency is in units of Hertz (cycles per second). According to Fourier theory, every periodic signal can be expressed as a sum of sinusoids at frequencies given by integer multiples of the fundamental frequency. For integers greater than 1, these frequencies are called harmonic frequencies, and the sinusoids at harmonic frequencies are online loans typically called harmonics.

All the examples of filters mentioned in Chapter 1 were LTI, or approximately LTI. In the following sections, linearity and time-invariance will be formally introduced, together with some elementary mathematical aspects of signals. Definition of a Signal Definition. A real discrete-time signal is defined as any time-ordered sequence of real numbers.


La télévision a changé le monde. Le temps est venu de changer la télévision. TVCI MTL est un regroupement préoccupé de l’état actuel des médias au pays, et plus particulièrement dans la grande région de Montréal. Nul besoin d’être expert pour jeter un coup d’œil sur le paysage médiatique et constater rapidement qu’une petite poignée d’entités privées contrôlent nos ondes. Notre rêve est de briser ce monopole et de construire une télé par et pour nos communautés. Cet acte de créativité devenant réalité est non seulement essentiel pour construire et desservir une communauté saine, diversifiée et dynamique, mais est également une condition indispensable à l’amélioration de la démocratie.

« Montréal et Canada ont absolument besoin de ce type de télévision reflétant le caractère pluraliste de la principale ville du Québec. »
