    MOSFET Board, reversible logic

    Hi. I have the need to drive two MOSFET boards in opposition. When signal from the signal generator (5v Arduino type signal) I want two have two MOSFET boards operation is opposed When signal is high MosFet 1 is on and MOSFET 2 is off When signal is low, MOSFET 1 is off and MOSFET 2 is On...

    Implement a simple circuit using logic doors

    I need to implement a circuit but Im having some trouble since Im novice on electronics. I have 4 inputs. A being ON/OFF switch. B is an Inibitor. C is an Emergency and D is not an adequate ocasion. In order to turn off the lamp I have to meet 2 conditions. Condition 1: Switch is ON (A)...

    [Solved] AND as logic switch?

    Hi Based on the logic table for AND gates, i should be able to use either as a simple digital switch. That is, say input 1 is running at 40khz, and input 2 is 1 Hz. Then, every second, our output should toggle between 0 for half a second, then 40kHz for half a second. Correct? **broken link...

    Designing a sequential circuit

    Any help on this problem would be very appreciated: So I am supposed to solve a push button problem and draw the circuit, using any gates and multiplexers. So the problem reads: Design a sequential circuit which will output Z = 1 for exactly four clock cycles each time a person pushes a...

    Programming a GAL with code for a lower spec device

    Hello everyone, I have a circuit and .jed file that requires a GAL16V8, however I don't have any of those handy, but I do have several GAL20V10's in stock. What sort of editing will I have to do to the .jed file (if any) to get this to work? Sorry if this is a stupid question, this is my first...
