What that flip-flop does, but mostly why those two NAND gates aren`t just inverters. and why the one on the bottom (and the inverter next to it) are even there. You should wait with accepting the answer and allow others to have a look and write up their....

The circuit takes its input from the "zero-crossing detector", which provides it with a 0-to-1-to-0 pulse to "set" the R-S flip-flop and release the ramp circuit (A to Ramp) for it to start the ascent of the timing ramp...
-
Dynamic‚ip-‚ops ignore pulses at their inputs that are shorter than 40 ns or do not have TTL levels. This means that TTL flip-flops are poorly suited to capturing noise pulses having unknown durations and magnitudes. Anyone who has ever tried to observe very....

Using just two NAND or inverter gates its possible to build a D type (or toggle`)‚ip-‚op with a push-button input. At power-up the output of gate N2 is at a logical 1`, ensuring that transistor T2 is switched off. When the push-button is pressed the output....

Optical toggle switch using a single Chip. Using dual flip-flop IC CD4027 employ a 555 based monostable circuit to supply input clock pulses. The circuit described here obviates this requirement. One...
-
This circuit "cheats" by using only two J-K flip-flops to make a three-bit binary counter. Ordinarily, three flip-flops would be used - one for each binary bit - but in this case we can use the clock pulse (555 timer output) as a bit of its own. When you....

In the circuit, N1, N2 constitute the RS flip-flop, and the trigger end is pin 8 and 13; N3, N4 form the controlled oscillator, only when N3`s pin 1 is high, the oscillator works. When the finger touching pad TP1 is bridging, N1 output`s pin turns to high....

This will drive a total of 42 LEDs. It is based on the assumption that the forward voltage of your LEDs is ~2. 2V, and that they will be bright enough with a forward current of ~21mA. If yours are a lot different, I will have to modify the design. The 2n3904....

We`ve already seen one example of a monostable multivibrator in use: the pulse detector used within the circuitry of flip-flops, to enable the latch portion for a brief time when the clock input signal transitions from either low to high or high to low. The....
