4017 circuits

understanding it; not understanding analog circuits, but understanding digital circuits. I learned this in school. The microcomputer principles and digital circuits are enough. But I doubt if you have the patience to read these two books. I don't know if there are any faster books. If you want to achieve this quickly, let's release it first. If you don't underst

frequency efficiency is very low. For 10 groups of common harmonic circuits, the capacitance values of each group of circuits are adjusted and no longer moved. Different common harmonic circuits are switched to achieve fast conversion frequency. Therefore, the efficiency can be improved indirectly. In addition, Channel 5 is originally a central five, and later i

addition to designing Logical Circuits, you can solve many logical problems in production and life, it also supports data processing, code conversion, and code conversion. Examples of applications are as follows. ① Logical truncation: when used and computed, you can extract part of the information from known information by selecting an appropriate logical constant. For example, you can separate the number of points from the ending number and intercep

process structure of the instrument, and a reasonable process structure, it can eliminate noise interference caused by improper PCB wiring design and facilitate installation during production. Debugging and repair. As there is no strict "Definition" or "Mode" in the excellent "structure", we will discuss the above issues for reference only. The structure of each instrument must comply with specific requirements (electrical performance. The system adopts the corresponding structure design scheme

maximum output power pmax=u2/(4XR). That is, when the load resistance is equal to the internal resistance of the signal source, the load can obtain the maximum output power, which is one of the impedance matching we often say. For pure resistor circuits, this conclusion is also suitable for low frequency circuits and high frequency circuits. When the AC circuit

CShort (? ) Multiple open-drain circuits, common with a pull-up resistor, which is known as a wired-or connection, can be lowered by pulling down the pin pin of any IO to make the output low. To output a high level, all outputs are high. This logic, which is the "line and" function, does not require additional gate circuitry to implement this part of the logic. schematic Chart 2 push-pull schematic diagram must be extern

The computer is composed of hardware and software which is indispensable.How to achieve within?First I'm going to tell you two conditions: a circuit that can perform a specific function, a programThen, can complete the specific function of the circuit: basically digital circuit and analog circuit mixing, digital circuit through the use of current voltage to control the components of the off and on (off is 0, open is 1), and then you can have a certain function of the circuit with these 0 and one

outputs the string to the console, and the task 1 runs in another thread. After the FirstTaskMethod is executed, the SecondTaskMethod continues. It is worth noting that multiple tasks can be started at the end of a task. That is to say, the task connection can be like a tree structure, as shown in the following code: 1: Task task1 = new Task(FirstTaskMethod); 2: Task task2 = task1.ContinueWith(SecondTaskMethod); 3: Task task3 = task1.ContinueWith(SecondTaskMethod); 4: Task task4 =
