Hello Everyone,I am generating 2 square waves of different frequencies and duty-cycle and when I multiply that 2 waveforms then the rising and falling time gave me peaks. Actually, I want to reduce the rise and falling time of the square wave. How I can do this kindly suggest me any solution to this.Thanks

[Worked on a reply & example intermittently, then noticed additional activity just before posting. I think I'm mostly addressing a different aspect of things, hopefully something below is helpful.] [And then when trying to post, I found that my connection had timed out hours ago and I lost most of what I wrote up. I'll at least post the example and try to summarize.] Closer to clarity, but still kinda confusing. Your msg #1 picture attachment shows waveforms that vary between +/-25 and +/-5 respectively. Your msg #7 shows something much more straightforward with digital signals that vary between (logical) 1 and 0. You speak of *multiplying* your square waves, which works out to be the same as a logical AND when you work with signals as they are shown in msg #7. You should deal with the signals in *logical* form as much as possible. If you need to scale to +/-5 or whatever, wait and do that as a very last step. Attached is a pretty simple example that generates a pattern like you showed in the msg #7 timing diagram. Some of the constants have a mathematical relationship to one another and in real code, some should be calculated based on the others. The vast majority of the code has to do with (1) generating the square waves and (2) converting them into a format that lets me display them in a digital waveform graph. The actual logical combination part is pretty much trivial. -Kevin P
