Anonymous users2024-02-10I suggest you do a solid tuition on everything except chapters seven – ten.
Digital circuits basically do not use the specific content of advanced mathematics, mainly to be logically clear, especially in sequential logic circuits, you need to have a clear concept of some basic content of algebra, such as equivalence relations, equivalence classes, and so on.
Signals and systems are math-intensive content. First of all, there is a lot of integration and differentiation in convolution, fourier transform, and laplace transform, and it is important to learn the basics of calculus well. Second, all Fourier analyses are based on the Fourier series of infinite series, and you can't do it if you don't understand it.
Thirdly, if you want to learn state variable analysis, you need to know about power series. Of course, linear algebra is also useful.
As for analog circuits, from a high point of view, it is necessary to be able to calculate a simple definite integral (used when finding power), and to be proficient in the knowledge of circuit principles, such as junction voltage method, loop current method, phasor method for sinusoidal steady state analysis, etc. This course requires both electrical and signal systems, and correspondingly requires a lot of mathematical foundation.
You can skip it for the time being, but if you want to learn about electromagnetic fields and other things in the future, you can watch it.

Anonymous users2024-02-09Because the foundation of electronic technology (3) the first one mainly involves the foundation of electronic technology, I have learned in high school, what circuit composition, current analysis, series of resistance, parallel, Ohm's law, Kirchhoff's law, superposition theorem, etc., from the second chapter onwards, the knowledge of high school is relatively little, the second chapter mainly talks about the principle of amplifiers, crystal diodes, transistors, the third chapter is integrated operational amplifiers, the fourth chapter is DC regulated power supply, the fifth chapter is the basics of digital circuits, and the sixth chapter is combinatorial logic circuits. Chapter 7 is the basics of sequential logic circuits, and Chapter 8 focuses on programmable logic devices.

Anonymous users2024-02-08Calculus and linear algebra.
Calculus is the branch of mathematics in advanced mathematics that studies the differentiation and integration of functions, as well as related concepts and applications. It is a fundamental subject of mathematics. The content mainly includes limits, differential calculus, integral science and their applications.
Differential calculus consists of the operation of finding derivatives and is a set of theories about the rate of change. It makes it possible to discuss functions, velocities, accelerations, and slopes of curves in a common set of notations. Integralism, including the operation of finding integrals, provides a general set of methods for defining and calculating area, volume, etc.
Linear algebra is a branch of algebra that deals primarily with problems of linear relations. A linear relationship means that the relationship between mathematical objects is expressed in a single form. For example, in analytic geometry, the equation for a straight line on a plane is a binary equation; The equation for the plane of space is a ternary equation, while a straight line in space is regarded as the intersection of two planes and is represented by a system of equations composed of two ternary equations.
A one-time equation with n unknowns is called a linear equation. A function with respect to a variable that is once is called a linear function. Linear relationship problems are referred to as linear problems.
The problem of solving a system of linear equations is the simplest linear problem.

Anonymous users2024-02-07Calculus Fourier series.
Since you said that it is the first semester of your junior year, then I advise you to focus more on professional courses, because professional courses also have to be studied well, and it is not too late to prepare for the next semester!!
1.Solution: f(x-a)=x(x-a)=(x-a+a)(x-a).
So f(x)=x(x+a). >>>More
I'd like to ask what the t in the first question is ...... >>>More
The first question is itself a definition of e, and the proof of the limit convergence can be referred to the pee. >>>More
An infinitesimal is a number that is infinitely close to zero, but not zero, for example, n->+, (1, 10) n=zero)1 This is an infinitesimal and you say it is not equal to zero, right, but infinitely close to zero, take any of the values cannot be closer to 0 than it (this is also the definition of the limit in the academic world, than all numbers ( ) are closer to a certain value, then the limit is considered to be this value) The limit of the function is when the function approaches a certain value (such as x0) (at x0). 'Nearby'The value of the function also approaches the so-called existence of an e in the definition of a value, which is taken as x0'Nearby'This geographical location understands the definition of the limit, and it is no problem to understand the infinitesimite, in fact, it is infinitely close to 0, and the infinitesimal plus a number, for example, a is equivalent to a number that is infinitely close to a, but not a, how to understand it, you see, when the chestnut n->+, a+(1, 10) n=a+ is infinitely close to a, so the infinitesimal addition, subtraction, and subtraction are completely fine, and the final problem of learning ideas, higher mathematics, is actually calculus, and the first chapter talks about the limit In fact, it is to pave the way for the back, and the back is the main content, if you don't understand the limit, there is no way to understand the back content, including the unary function, the differential, the integral, the multivariate function, the differential, the integral, the differential, the equation, the series, etc., these seven things, learn the calculus, and get started.
