Question 3:

A)Design a BCD counter.
-The circuit counts from 0 to 9, then resets back to 0 to restart the counting sequence.
-The circuit has one input run/stop. If the input is 1, the eounter will count. If the input is 0, the counter will freeze in its current location until the input is set to 1 again.
-The circuit has one output. It becomes 1 when the counter completes a cycle and starts the next one. Otherwise, that output is 0.

B)Design a system that will deteet the sequence 110 anytime it occurs in an input wire x.

Write a program sequence that will test the byte STATUS and branch to ROOTINE_1 if bit 1, 2 or 4 is 1. Otherwise, it is branch to ROUTINE_2 if both bits 1 and 3 are 1 and to ROUTINE_3 if both bits 1 and 3 are 0. In all other cases it is to exeute ROUTINE_4. Assume that the routines are more than 128 bytes long. Also give a flowchart of the sequence.

##### Para maximizar la transmisión de potencia a la línea la impedancia de entrada de la línea...

Para maximizar la transmisión de potencia a la línea la impedancia de entrada de la línea debe ser Zin=Zg*.

Para conseguir esta impedancia de entrada proceda como se le indica en los apartados c) y d).

Determine:

c) La mínima longitud de la línea (en longitudes de onda) para que la parte real de su admitancia de entrada sea 8×10-3 Ω-1. Determine el valor de dicha admitancia de entrada. (10 puntos)

Si no ha resuelto el apartado (a) tome Z0=50Ω.

d) La admitancia Y que debe colocarse en paralelo a la entrada de la línea para que el generador vea una impedancia de entrada a la línea igual al conjugado de su resistencia interna. Verifique que efectivamente ahora Zin=Zg*. (5 puntos)

Si no ha resuelto el apartado (b) tome Yin=0.008+j0.016 Ω-1.

e) La potencia media entregada a la carga en las condiciones del apartado (d). (3 puntos)

To maximize power transmission to the line the line input impedance must be Zin = Zg *.

To achieve this input impedance proceed as indicated in sections c) and d).

Determine:

c) The minimum length of the line (in wavelengths) so that the real part of its input admittance is 8 × 10-3 Ω-1. Determine the value of that input admittance. (10 points)

If you have not solved section (a) take Z0 = 50Ω.

d) The admittance Y that must be placed in parallel to the input of the line so that the generator sees an input impedance to the line equal to the conjugate of its internal resistance. Verify that effectively Zin = Zg * now. (5 points)

If you have not solved section (b) take Yin = 0.008 + j0.016 Ω-1.

e) The average power delivered to the load under the conditions of section (d). (3 points)
