Hi, I am new to this forum so I hope you guys can help. I need a circuit that will detect a signal pulse from another circuit with a max voltage of 9V that will trigger a power supply to supply power to output as long as pulse is on and stop the power output when pulse stops, also the output power needs to be adjustable from 1 watt to 100 watts. an example would be pulses are at 50Hz and the power supply pulses to power output at exactly 50Hz but power is on to output during the trigger pulse and off when there is no pulse detected. output will be use to power antenna or coil, the input pulse is not important to the design of this circuit as long as the circuit will switch power on and off with the input pulses, thanks.
