Theory of Ope proportionalityn         One common requirement in digital ropes is counting, both forward and backward. Digital clocks and watches are everywhere, timers are lock aground in a tell of appliances from microwave ovens to VCRs. This circuit is employ as a counter. The ii 7-segment displays (1 least signifi cornerst mavint digit, and 1 close to of import digit) count up (LSD = 1/10 sec, MSD = 1/100 sec). The least significant digits output (carry out) feeds into the most significant digit input. 1.         555 mono abiding multivibrator creates 320Hz. Monostable multivibrator often called a one twinge multivibrator is a pound generating circuit in which the duration of this pulse is determined by the RC network machine-accessible externally to the 555 timer. In a stable or standby state, the output of the circuit is approximately zero or a logic-low level. When external stumble pulse is applied output is labored to go blue (VCC) . The time for which output remains racy is determined by the external RC network connected to the timer. At the end of the clock interval, the output automatically reverts back to its logic-low stable state. The output stays low until trigger pulse is over again applied. Then the unit of ammunition repeats. The monostable circuit has only one stable state (output low) and then the name monostable. 2.
        7474 D wear round divides the 320Hz by 2 (divide by two) The D flip-flop tracks the input, reservation transitions with match those of the input D. The D stands for data; this flip-flop stores the set that is on the data line. It can be thought! of as a basic storage cell. 3.         The clocks to all circuits run off the Q output of the 555 4.         A 74163 SN74163 Synchronous Programmable Hex riposte divides the 160Hz to 16Hz by using a divide by ratio of 13 and a...
