How can I produce 20 to 60 hz, the high level of 1 to 10 ms adjustable square wave signals? As far as possible need not the FPGA or microcontroller, you ask bosses predecessors to reassure the rush!

CodePudding user response:

555 piece of integration is convenient, information on the Internet is very much also,

CodePudding user response:

555 can indeed, simple and quick

CodePudding user response:

I made a multivibrator 555, frequency 50 hz, power supply voltage of 5 V, according to the data of the output level should be less than 1-3 V power supply voltage, but use Multisim simulation output level jump between 5 V and 0.5 V, if the frequency tuning work won't be so, why is this excuse me? There is something wrong with the simulation model is?

Who will know you say that?
