    60 Hz sine wave to TTL clock signal (pulse shaping help)

    Would a half wave voltage recitifier and voltage divider work, using a diode and two resistors? The output is fed into a schmitt trigger. it doesn't need to be 50 percent duty cycle. I am using it as a 60 Hz clock signal (ie vertical transitions).

    60 Hz sine wave to TTL clock signal (pulse shaping help)

    I am designing a simple circuit that will take a 12 V 60 Hz AC sine wave and turn it into a 60 Hz clock signal for a TTL clock. I have Schmitt trigger inverters or buffers to use. I am unsure on how to interface the sine wave signal to the Schmitt trigger. I am thinking that I need to rectify...

    60 Hz sine wave to TTL clock signal (pulse shaping help)

    I am trying to design a circuit to take a 15 V ac sine wave and get a TTL clock signal that is +5 V. I want to use a Schmitt trigger inverter, because those are available. I don't have much background in analog circuit design. I drew up a basic design: Basically, its a half-wave rectifier, and...
