Differential equation involves derivatives of function. Difference equation involves difference of terms in a sequence of numbers. People sometimes construct difference equation to approximate differential equation so that they can write code to s. analog computer A device that processes infinitely varying signals, such as voltage or frequencies. A thermometer is a simple analog computer. As the temperature varies, the mercury moves correspondingly. Although special-purpose, complex analog computers are built, almost all computers are digital. Digital methods provide programming flexibility.

I'm trying to build a circuit to solve the differential equation x''+2x'+x = f(t), where f(t) is a sine wave with frequency 5Hz and amplitude V. I am supposed to get a sine/cosine wave (as the diff. eq is just the same as the ove governing . All mathematical operations necessary to the solution of ordinary differential equations can be built up from addition, multiplication by a constant, and integration. * As will be shown later, the analog computer can perform these operations and thus is a convenient device for the solution of differential equations.

Example 1. Solve y= 0. Solution: p(r) = r3 implies 1, x, x2 are solution atoms. They are independent, hence form a basis for the 3-dimensional solution y= c 1 + c 2x+ c 3x2. Example 2. Solve y00+ 4y= 0. Solution: p(r) = r2 + 4 implies cos2xand sin2xare solution are a basis for the 2-dimensional solution space with y= c 1 cos2x+ c 2 sin2x. File Size: 92KB. Analog solution. Some differential equations are easily solved by analog computers. These are extremely fast and so suited to 'real time' control problems. Their disadvantages are limited precision and that analog computers are now rare. Below we show two examples of solution of common equations.

Analog computers may not be as accurate as digital computers, but they are incredibly fast at solving differential equations. Because analog computers solve the whole equation at once, we could change the frequency or shape of the forcing function and have, with an unnoticeable delay, the new solution.

An analog computer or analogue computer is a type of computer that uses the continuously changeable aspects of physical phenomena such as electrical, mechanical, or hydraulic quantities to model the problem being solved. In contrast, digital computers represent varying quantities symbolically and by discrete values of both time and amplitude.
