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 ...
Verification is intended to check that a product, service, or system meets a set of design specifications. [6] [7] In the development phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service, or system, then performing a review or analysis of the modeling results.
A hybrid system has the benefit of encompassing a larger class of systems within its structure, allowing for more flexibility in modeling dynamic phenomena. In general, the state of a hybrid system is defined by the values of the continuous variables and a discrete mode .
Clapton asked Jim Marshall to produce a combo amplifier with tremolo, which would fit in the boot of his car, and one of the most famous Marshall amps was born, the "Bluesbreaker" amp. [7] This is the amplifier, in tandem with his 1960 Gibson Les Paul Standard (the "Beano"), that gave Clapton that famous tone on the John Mayall & the ...
The sensors which transimpedance amplifiers are used with usually have more capacitance than an op-amp can handle. The sensor can be modeled as a current source and a capacitor C i. [4] This capacitance across the input terminals of the op-amp, which includes the internal capacitance of the op-amp, introduces a low-pass filter in the feedback path.
Nortel Meridian is a private branch exchange telephone switching system. It provides advanced voice features, data connectivity, LAN communications, computer telephony integration (CTI), and information services for communication applications ranging from 60 to 80,000 lines.
A simple and robust solution is to use paralleled voltage followers, which by design have exactly unity gain, driven by a common voltage amplification stage. In addition, small resistors (much less than the load impedance, not shown in the schematic) are added in series with each amplifier's output to enable proper current sharing between the ...
In 1960, Ampeg introduced the B-15, a bass combo amplifier with an innovative flip-top function, invented and patented by Oliver. The B-15 was the first in the company's Portaflex series, and after becoming the preferred studio amp of session musicians like James Jamerson and Chuck Rainey.
