In the first timing diagram, when S becomes 1, after 10ns QN becomes 0, and 10ns later Q becomes 1. Now, draw the S-R latch with NOR gates, write initial values near corresponding letters (S=0, R=0, Q=0, QN=1), change S to 1, and try to understand what changes you see. If you struggle, look at the timing diagram you shared.

Oct 23, 2013 · In a typical single-output SR latch, the state of the output when S and R are both active will either be defined as high, or defined as low; in an SR latch with a complementary pair of outputs, the state of each output in the "R and S both active" condition may be …

Apr 21, 2020 · I have a push button switch (single-pole double throw) connected to a latch as follows: I was thinking about the timing diagram of the circuit above (above image is the default state of the circuit when the switch hasn't been pressed down). Would this timing diagram sufficiently describe the output given the signals below?

Jun 12, 2017 · At t0: S = 1 and Q = 0. This 1 and 0 goes into the top nor gate and after 1.4ns, Q’ = 0… hence Q’ is changed from its initial value 1, to 0 after 1.4ns (as seen on the timing diagram). * Note that while this was happening, (from t0 to 1.4ns), R was 0 and Q’ was initially 1.

Sep 23, 2024 · How to make the simplest non-inverting latch The recipe is extremely simple and intuitive - we connect the output of a non-inverting amplifier (a 1-input logic gate or buffer BUF) to its input . Thus, we force it, with the help of "self-reinforcing positive feedback" to maintain (remember) its output voltage in one of two possible values - 0 V ...

Nov 16, 2018 · A given pencil might be unbalanced in a way that makes its fall predictable, but in general you cannot predict the direction that a pencil will fall. Random variations in transistor parameters will cause the latch to eventually prefer one state or the other but in general the initial state of a latch at power-up cannot be predicted. \$\endgroup\$

May 19, 2021 · Below is the verilog code that I wrote to implement a simple SR Latch. Note that I assumed different gate delays for the same NOR gate. (#10, #5) module rs_latch( input S, input R, output ...

Oct 4, 2018 · JK latch is similar to RS latch. This latch consists of 2 inputs J and K as shown in the below figure. The ambiguous state has been eliminated here: when the inputs of Jk latch are high, then output toggles. The output feedback to inputs is the only difference we see here, which is not there in the RS latch. Compared to the JK flip-flop:

However, to address the specific question of the latch, it's simply a matter of creating an S-R latch that only switches on the "final" states (0,1) and (1,0). The latch will change state the first time the new final state is reached. If the make occurs first then the bouncing between the initial state and (1,1) will cause no change to the latch.

Apr 18, 2019 · A level-triggered circuit (I would call that a Latch) can be thought of as a RS-FF with both inputs gated by the enable input (CLK in this diagram): In this circuit, a simulatenous 00 -> 11 transition of the hidden 'inputs' of the cross-coupled NANDS still causes a race condition.
