Solid-State Pulse Circuits by David A. Bell eBook - The term solid-state pulse circuits is typically associated with sensors that are mathematically modeled in the form of mathematical models which understand the physics behind how they work. The term can also refer to pulse shaping circuits in which pulses are either shaped in real time, or pre-shaped similar to digital signal processing (DSP) circuitry. To address these two different meanings, this article will clearly show what a solid-state pulse circuit is and discuss two types of them: those that process pulses on a real time basis and those that process them pre-shaped. The term solid-state pulse circuits is often loosely used in conjunction with the term of electrical transients, which is more closely associated with physical mechanisms that are modeled for processes such as lightning; but more accurately, the physical conditions behind electrical transients are fully understood. Solid-State Pulse Circuits (hereafter referred to as SSC) are more useful in terms of applications by patterns of integration. They make use of solid-state components that have operation in the presence of electrical transients with gaps that contain or in place of electrical transients. This type of SSC is an important form in which the DSP instructions are applied to control hardware. But in most cases, a real time circuit is a more useful form. Since a solid-state device operates with electrical transients without any impact from these transients, the energy involved in the electrical disturbance is significantly less than that of a traditional device. Therefore, the manufacturer can use smaller and more powerful components for this operation. The SSC may be used to amplify electronics signals and to identify any change in signal amplitude caused by an outside condition . The two types of SSC can be created with some real time processing and some pre-formed processing. A pattern circuit will mainly use the pre-formed types of SSC while a real time circuit will mostly use the pre-formed types of SSC. The operation of SSC is based on the model of the electrical system of the device. The method is quite simple, but accurate. The manufacturer can use solid-state components in their own circuits, knowing that they are not affected by electrical transients occurring in the real world. An SSC can be used to identify a change in the operating state of an electronic device that otherwise would not identify. The mathematical model is based on several assumptions about how an electrical system operates. It assumes that current has a constant value until it hits a resistance. It assumes that there is a third component to the device that holds voltage constant and current changes. The mathematics behind the model is based on linearizing the current and voltage, and solving for the third component to get back to a solution for current. The model effectively becomes a set of differential equations, which can be solved with Least-Squares or other methods. There are newer models that use even more advanced mathematics, such as Differential Equations (DEE's), but these models take still more time for calculations than using linearized equations. There are two types of SSC: One in which circuit elements operate in series without any additional components, and another in which elements operate in parallel with additional components. 8eeb4e9f32 58
