T flip flops
I have seen some of the questions like ISRO 2017-ECE T- Flip flops saying that T flip flops are connected in cascade. But, I am not able to understand what is the circuit diagram... ? I mean how are they connected ? Is the output of one being fed into the input of other, or the output of one is fed into the clock input of other ? Please provide me with a circuit diagram. Thank you.

MadeEasy Test Series 2018: Digital Logic - Flip Flop
State-Diagram of a flip-flop is shown below: The next state equation of the above flip flop will be (X represent input) My doubt:- In truth table in input 00 the next state will be 1. Now this 1 is because of the state number 1 or because ... written on the edge as 0/1 ? The circled part is the state number or the output(1) from the edge 0/1 ?

Digital Logic: Counters
Consider the following question: My explanation: A clock cycle time should be large enough that all flip-flops can come in a stable state before the next clock cycle starts. Suppose cycle 1 is just completed and cycle 2 is just about to start: 1. to ... on the following link, it is $\frac{1}{20ns}$. Can someone explain, please? https://gateoverflow.in/26442/gate1991_5-c
