Remember that 7490 decade counters respond only to the pulses that go from 1 to 0 and notice that this case only happens in the BCD code above when the output changes from 9 to 0 (the Most significant bit changes from 1 to 0). So, we'll just connect the clock input of the 2nd counter to the most significant bit of the output of the first counter.

Digital Electronics Lab (Pattern 2015) Pune Vidyarthi Griha's COLLEGE OF ENGINEERING NASHIK - 4 Prepared By: Prof. Anand Gharu In the ring counter the outputs of FF-3 were connected directly to inputs of FF-0 i.e. Q3 to J0 Q3 to k0. Instead if the outputs are cross coupled to the inputs i.e. if Q3 is connected to k0 & Q3 is connected to J0 then the circuit is called as twisted ring counter.

An improved method of operating a digital timer using line currents of different frequencies such as 50 and 60 hertz. The line current is rectified and converted into square wave pulses at the line current frequency. Upon actuation of a start switch to initiate the timing cycle, the logic circuitry is cleared and synchronized at the line current frequency.

A 1 Hz (signal at every 1 second interval) square wave from an astable multivibrator is applied as a digitalclockcircuitdiagram signal to the S0 counter which counts from 0 to 9 after every second. After 9, the values reset back to 0. Whenever S0 (4 bits) becomes 0000, a clock signal needs to be generated.
First complete the 0 - 9 counter using 7493 with a 1 Hz square wave as clock from a 555 timer as in step 9. Once that counter works, connect the reset terminals of 7493 (terminals 2 and 3) to the two inputs of a NAND gate (7400 will do). The output of.
