Please, I want the solution in two ways:
Method 1 (without the Smith chart):
Method 2 (using the Smith chart):
A short circuit stub of length 0.04λ is used to match a 50 Ω lossless line to a load ZL = RL + j30 Ω. Use Smith chart to find:(a) The distance between the stub and the load.(b) The value of RL .
THE FIRST PAGE OF THIS QUESTION SECTION BELOW IS THE FIRST IMAGE UPLOADED, WHICH SHOWS A digital synchronous sequential circuit and then comes the questions below:1B) Suppose the flip-flops are 74F74 devices and the AND gates are 74F08 devices. Let maxtpd,D=9ns, maxtsu,D=3ns, and maxtpd,AND=6ns. What is the maximum clock frequency at which the circuit can operate reliably?
2) Compare serial transmission and parallel transmission and discuss their advantages and disadvantages.
3) Explain briefly how the slave can protect itself from being overwhelmed by the master in I2
4) A hypothetical logic family has the following specifications.
VOH=4.6V VIH=4.0V
VOL=0.5V VIL=1.0V
IOH=-1mA IIH=50μA
IOL=8mA IIL=-0.6mA
(4a) What are the noise margins?
(4b) What is the fan-out capability?…
