Embodiment Construction

[0014] Embodiments of the invention include devices, methods and products for linear signal conditioning. The term "signal" as used herein should be broadly construed to include any means of conveying data from one place to another, such as electric currents or electromagnetic fields, including, but not limited to, switching on and off direct or alternating current or including An electromagnetic carrier wave of one or more data streams. For example, data can be superimposed on a carrier current or carrier wave by means of modulation, which can be done in analog or digital form. The term "data" as used herein should also be broadly interpreted to include any type of message or other information, such as, without limitation, audio, text and / or video such as sounds.

[0015] figure 1 A preferred embodiment is shown. The input signal a is supplied to the digital signal processor 10 . The digital signal processor 10 includes an analog-to-digital converter 11 for digitizing the...

Abstract

An apparatus, method and article of manufacture for linear signal conditioning are shown. The input signal is adjusted by providing one or more non-linear current sources and adjusting at least one of the one or more current sources to output a signal based on the one or more input signal characteristics. Adjustment of the output signal includes both amplification and attenuation.

Description

technical field [0001] The present invention generally relates to the adjustment of linear signals, and more particularly to the amplification and attenuation of linear signals. Background technique [0002] Generally speaking, conditioning (amplifying or attenuating) electromagnetic signals is a function of an electronic component or system. Tuning can be used for any number of systems, and is usually accomplished by linear or non-linear techniques. Linear techniques generally provide an output signal that is very close to the input signal except in magnitude. Nonlinear techniques generally provide output signals that do not have close proximity to the input signal. [0003] Non-linear or linear amplifiers may be useful. Nonlinear amplifiers can be used for on / off amplification—that is, in situations where it is not necessary to produce an exact amplification of the input signal, but only to amplify the signal. Linear amplifiers can be used in situations where accurate,...
