    Demultiplexer 8 to 1: Solve Truth Table

    I understand a demultiplexer has only one input and many outputs and a multiplexer only has one output and many outputs, I figured out my truth table for a 8 to 1 multiplexer which is S2 S1 S0 OUT 0 0 0 D0 0 0 1 D1 0 1 0 D2 0 1 1 D3 1 0 0 D4 1 0 1 D5 1 1...

    Drawing a KMap for f(A,B,C): Step-by-Step Guide

    thanks for the help I than simplified it to (AB + A'B' + A'C), but when I use a simplifing program it says that I'm correct or it could also be (AB + A'B' + BC). I'm little confused with this one. My professor said once we simplified it we were suppose to find the Static 1 Hazard with this...

    Drawing a KMap for f(A,B,C): Step-by-Step Guide

    Draw a Kmap for f(A,B,C) = E m(0,1,3,6,7) I've had enough expirence with kmap through my digital courses to understand them, but I've never seen them described this way, AB 00 01 11 10 C 0 1 0 1 0 C 1 1 1 1 0 Is this...

    Unsigned vs Signed byte numbers

    some one tell me if this is right this is the binary number 11111111 unsigned = 255 (decimal) signed = -1 (decimal) is this correct because in my book it says to take the opposite so all 1's become 0's then you add 1 in the LSD.

    Calculating Total Momentum of Objects Moving in Different Directions

    Homework Statement A 4.00 kg ball is moving at 3.00 m/s to the NORTH and a 5.00 kg ball is moving at 2.00 m/s to the NORTHWEST. The total momentum of the system is: I have a very bad book that doesn't discuss how to deal with total momentum with relationship to different directions other...

    Calculating Momentum of a Falling Mass: 30.00 kg Object from 4.00m Height

    Homework Statement A 30.00 kg mass falls from a height of 4.00m. The momentum of the mass just before it hits the ground is? Homework Equations obviously p=mv The Attempt at a Solution I just can't figure out how to get a velocity for this formula?

    JK FF: Why Duty Cycle is Always 50%?

    Why is the duty cycle out of the JK flip flop 50% even if the input to the JK flip flop is not 50% I couldn't find a direct solution in my textbook, I understand if anything above 50% goes into the JK input the output will be 50%, but what if the input is below 50% will increase to 50% just...

    Want a up counter but have a down counter

    I can't figure out why? I inverted every CLK signal and nothing happens I switch every Q' to Q and nothing works help, me its a 8 bit up counter but Its counting down I have 3 jks

    Astable Multivibrators/Oscillators

    f= 1/T I knew that part just figured to write the entire question, i figure out that Ra= 100 and Rb= 94 and C1= 1 uf so should I use the following formula for the high and low high = 0.67 (Ra*C) low = 0.67 (Rb*C)

    Astable Multivibrators/Oscillators

    I have a very confusing teacher for my electronics lab, I am suppose to design an astable multivibrator with an output frequency of 5KHz and a duty cycle of 70% using a 555 timer. Thats what I'm suppose to do in lab I have the following pre-lab questions that I can't find information for...

    How do I safely build a variable DC power supply for my electronics projects?

    I'm taking an intro electronics class and I'm really enjoying it. I want to be able to work with electronics in my garage, I have a proto-board and but I would like to build a power supply that can go from 1vdc to 15vdc, this is what my class has. I've looked on the net for instructions, but...
