The 555 circuit can be generally classified into three categories in terms of application and working mode. There are many different circuits for each type of work. In practical applications, in addition to a single type of circuit, many different circuits can be combined, such as multiple monostable, multiple bistable, monostable and unstable, bistable and unstable combinations. As a result, the circuit becomes more complicated. As shown, the pulse error detector circuit design consisting of 555 circuits is shown.
