@TheMW The \$7.5\:\Omega\$ comes from the Thevenin of \$30\:\Omega\$ and \$10\:\Omega\$. Both sides have the same two resistance values, so the Thevenin of the left and right sides are the same value,...

@ursusd8 That's a good question to ask. One guess may be that said engineer(s) is/are gone because new financiers bought the company to make a short term profit, let go of their high paid, "difficult,"...

Since this is certainly a schoolwork problem, the question becomes, "What have you been taught to apply here, whether in class or through the use of textbooks?" You haven't even so much as described...

The AN6651 is a very small-scale version that is designed for tiny DC motors, such as those for cassette tape players. But it illustrates some of the behavioral complexity of what you are asking about.

@amit I've provided an answer that shows you how to read the circuit. The first step I took was to redraw it so that things were just a tiny bit easier for me to read. The next step was simply to spot...

I believe what you have is a subset called transmission parameters. Is it the case that there are only Z1 and Z2 values?

@SmallFreeRange Would this get the job done? That will work if and only if B always pulses within every A.

@PeterCordes Check out the R2000, which is what I used. Separate I and D cache. I also worked at Intel on the BX chipset. This would be circa year 1998-ish, around the PPro/P II period. I'm slightly...

Without looking over the schematic, the on/off chattering behavior is consistent with the lack of hysteresis.

Only even values? Or only odd values? Do you want to exceed a decimal digit? Or wrap around before getting into non-BCD values?

@sribasu Just to be clear, you want hysteresis to avoid the chattering. Lacking it is the reason for the chattering behavior.

Try adding a pull-down resistor, about 15-22 kOhm, from base to ground and adding a simple diode across the coil -- arrange the diode so that it's anode is towards ground and the cathode towards the...

@sribasu The idea is added. It's only a basic behavioral pointer. Details matter and you'll need to work those out in your case.

Show us how are you handling just one of the bandpass filters, with gain adjustment, while retaining the Butterworth behavior. I'd like to see what you are using to get there.

With tic-tac-toe, why aren't you just using the usual search tree, possibly with pruning? Hmm. Never mind. Are you making a state machine?
