    hello
    my exam is tomorrow and I need helo in this problem please
    Thank you

    1-
    Find the logic function of the RTL gate shown below. Assume V​
    CC = 12 V, RC = 1 KΩ , RB = 10 KΩ, and that the Zener diodes drop 4.7 V when conducting.
    NAND b) NOR c) AND d) NOT e) OR

    2-

    Find the output level (in V) that corresponds to LOW in the gate and the output that corresponds to HIGH.
    a) 0.5 b) 0.7 c) 1.2 d) 0.2 e) 1 LOW
    a) 12 b) 11.3 c) 6.6 d) 4.7 e) 15 HIGH

    3-

    Find the power drawn by the gate (in W) from the V​
    CC power supply when only one input is high in the circuit.
    a) 0.0118 b) 0.222 c) 0.142 d) 2.05 e) 0.0148

    I need to understant I do not just want the answers..

    Thank you

    RTL? Like the ones that were used 50 years ago? Ha, ha, ha, ha, etc.
    Tell your teacher to get more modern quizes.
