3 SR NOR flip flop Working of SR NOR flip flop The circuit diagram of the SR NOR flip flop is shown in fig.3. The excitation table for SR flip flop is given below. The inputs are Q n and Q n+1 and outputs are S and R. The characteristics table for the SR flip flop is given below.Įxcitation table is determined by the characteristics table. While dealing with the characteristics table, the clock is high for all cases i.e CLK=1. Q n+1 represents the next state while Q n represents the present state. Characteristics table for SR Nand flip-flopĬharacteristics table is determined by the truth table of any circuit, it basically takes Q n, S and R as its inputs and Q n+1 as output. The truth table of SR NAND flip flop is given below. holding previous values.Ĭase 2: if CLK=1 then S*= and R*=, now there will be 4 more cases depending upon the values of S and R.Ĭase 2(a): S=0 and R= 0 then S* and R* both becomes 1 and we get outputs Q and holding memory state.Ĭase 2(b): S=0 and R=1 then S*=1 and R*= 0 then we get Q= 0 and =1, we get both outputs as complement of each other.Ĭase 2(c): S=1 and R=0 then S*=0 and R*=1 them we get Q= 1 and =0.Ĭase 2(d): S=1 and R=1 then S*=0 and R*=0 then we get Q and in the invalid state i.e. Now we will understand the working of SR NAND flip flop by taking consideration into the SR NAND latch.Ĭase 1: Now if CLK is 0 then S*=1 and R*=1 and here S and R will be treated as don’t care conditions, then we get Q and in memory state i.e.

Since flip-flops are controlled by clock transitions, therefore we will provide a clock to our SR flip flop circuit. var clock = $('.your-clock').Likewise SR latch, SR flip-flop can be constructed by using cross-coupled NAND and NOR gates.

It works a typical jQuery plugin, but instead of returning a jQuery object, a FlipClock object is returned. įlipClock.js requires jQuery for DOM manipulation. The minified source contains all the clock faces for maximum portability. The following are the logical requirements that were considered when creating the API.Ībstract everything into reusable objectsįull-Featured Developer API to create custom “Clock Faces”įlipClock.js requires a few files to work properly. After reviewing as many of the existing solutions as possible, it was determined a proper extendible API needed to be written to create any kind of clock or counter (and the flip effect is just cool). Some libraries have a huge cascade of conditionals, while others simply hard-code too much into their scripts. (Besides the domain was available, who could pass it up?). So why use this library when there are many others with the same name? Well, this library was created because the other solutions weren’t abstract enough to provide a deep level of customization without rewriting the code.
