i have to suggest a circuit with a photocell that has to send to 200m a signal that ranges between those values... moreover it has to be a series of pulses... at the end i have to suggest a data trasmission... that's all...
however thanks... i'll look better those sites...
i don't know... i mean it's an exercise where i have to design this circuit... i told you everything i know... i don't know anything about lasers... what i know and have studied is especially operational amplifier and its applications (comparator, filters, etc)... then modulations and...
hey everyone
how can i make a circuit that can relay to a range of 200m a signal generated by the commutation of a photocell.
this signal has to be a series of voltage pulse and they can range between 0 and 40mV.
can someone help me???
