Rtl-level 4-bits Binary Adder-Subtractor Rtl-level 4-bits Binary Adder-Subtractor symbol
value of K is set to true or 1, the Y0⨁K produce the complement of Y0as the output. So the operation would be X+Y0', which is the 2's complement subtraction of X and Y. It means when the value of K is 1; the subtraction operation is performed by the binary Adder-Subtractor...

Referring now to FIG. 10, the binary summation or subtractor circuit 94 is illustrated. This circuit 94 comprises four bit adder circuits 154, 156 and 158, which may for example comprise integrated circuits of the type generally designated 74LS83. It will be seen that the interpolating signal...
If the eight levels of the multi-level pulses are ± 0.5, ± 1.5, ± 2.5 and ± 3.5, a "by 3.5" reducing subtractor 31 must be inserted in coder 30 before its output 29. The two partial words resulting from the synchronization word 00011 are always transmitted by direct conversion. ...
first subtractor means, coupled to said analog/digital converter and said second delayed signal, for subtracting said second delayed signal from said digital image signal to obtain a first subtracted output; and first adder means, coupled to said first subtracted output and to an output of a th...
We propose schemes for binary adder, subtractor and parity checker using optical logic gates. These schemes could be useful for calculations using optical systems. Utilizing optical logic gates, we can achieve functions of binary adder, subtractor and parity checker of high-speed optical signals. ...
CONSTITUTION: The multistage 2-ary adder/subtracter constitutes groups by pairing a stage (n) and a stage n+1 and each group is provided with carry propagation signal outputs Pn , Pn+1 and carry generation signal outputs Gn , Gn+1 . Then in response to the carry interruption signal, ...
