pulse

I am looking to have a period of say 60secs, and within that 60 secs a pulse of 20khz square wave for 20 secs. That pulse of 20 secs can be anywhere within that 60 secs. And then repeated. I am lead to believe 3 x CD4047 can do it ( a bit like using 2 x NE555) but I cannot find anybody doing...

Hello everybody, So I can't seem to figure this one out. I have a card reader (Nayax Onyx) with a constant 9v on pulse cable. I have a 12v relay switch. https://www.otronic.nl/nl/relais-module-12v-2-kanaals.html Connected 9v pulse cable to IN, 12vdc and -12vdc to power the relay coil...

I use ADS to generate eye diagram. How do I specify that I only want to generate the eye diagram at specific time frame. For example what if I want the diagram from 50~100 nsec ? Below the eye diagram is the default generated from equation based on the transient simulation time from 0~200 nsec.

How can I create pulse DC current and is adjustable from 60pps to the khz range @60v, 1amp max? I'm thinking of something similar to my TIG welder at work, which is capable of controlling not only the pulses per second, but the ramp-up and ramp-down times. I have a Ridon Rd6018 power supply, a...
