Impulse signal

  1. Jan 27, 2007 #1
    i am working with an encoder that says its output is impulse(ttl). i'm not quite sure what this means. is it just a digital signal? how does it work? any help you can give me would be great.

    TTL level is a digital signal, just 5 volts when on, and 0 volts when off.

    Impulse means it will go high and then low rather than stay high.
    TTL is the digital levels.
    So yes it is just a digital output
