Circuit components such as amplifiers can be tested using the two-tone method with a test setup like that shown in the figure. Two signal generators, set to two different frequencies F1 and F2, are fed into a power combiner through circulators. The combiner needs to have good isolation to prevent the signal from one generator being sent to the ...
For example, in order to match an inductive load into a real impedance, a capacitor needs to be used. If the load impedance becomes capacitive, the matching element must be replaced by an inductor. In many cases, there is a need to use the same circuit to match a broad range of load impedance and thus simplify the circuit design.
The Roland Micro Cube, left, a small and portable digital modeling amplifier. Digital amp modelers Standalone modeling devices such as the Line 6 POD and Fractal Axe-FX digitize the input signal and use a DSP, a dedicated microprocessor, to process the signal with digital computation, attempting to achieve the sound of expensive professional amplifiers in a much less costly and more compact ...
Digital signal processing (DSP) is the use of digital processing, such as by computers or more specialized digital signal processors, to perform a wide variety of signal processing operations. The digital signals processed in this manner are a sequence of numbers that represent samples of a continuous variable in a domain such as time, space ...
A DSP evaluation board, sometimes also known as a DSP starter kit (DSK) or a DSP evaluation module, is an electronic board with a digital signal processor used for experiments, evaluation and development. [6] Applications are developed in DSP Starter Kits using software usually referred as an integrated development environment (IDE). [7]
The bootstrap circuit uses a coupling capacitor, formed from the gate/source capacitance of a transistor, to drive a signal line to slightly greater than the supply voltage. [10] Some all-pMOS integrated circuits such as the Intel 4004 and the Intel 8008 use that 2-transistor "bootstrap load" circuit. [11] [12] [13]
The drive units (T27, B110 and B139) were sourced from KEF in kit form, and two KEFKIT3 kits were judiciously used for each cabinet. [1] Note 3 ] However, Linn found the T27 tweeter too fragile and replaced it with the more robust and better-sounding D2008 from Scan-Speak after a very short run; [ 1 ] the Scan-Speak tweeter was later changed to ...
These signals are combined in the amplifier circuit to yield a wide band signal extending from DC to over 50 MHz. (Wedlock & Roberge 1969, p. 154) The Tektronix A6302 current probe and AM503 amplifier combination is an example of such a system
