Modern complex systems are normally constructed by interconnecting sub-units.
Therefore the systems engineer is often not too concerned about the details of what is inside these sub-units, provided it does what it says it will do 'on the tin'.
The systems engineer is primarily concerned with what happens when these sub-units are joined together.
To enable this, the sub-units are normally represented by 'Equivalent Circuits' with the appropriate parameters given by the manufacturer of the sub-unit as part of its specification data sheet.
Q. Explain about Differentiator? Shown in Figure is a differentiator which is obtained by replacing R1 in the inverting amplifier of Figure by a capacitor C. Assuming ideal op-
Quite often an amplifier is used as a component of an amplifier circuit. Consider the amplifier circuit shown in Figure, which contains an amplifier block as an internal component.
When sizing wire, one of the most difficult tasks is to calculate the electrical load that will be present on the conductors. How do you decide what size wire to use? What two fact

(a) Figure shows a circuit containing an amplifier block. Find the open-circuit voltage amplification of the circuit. (b) Let the output terminals be connected to a load resista
(a) A universal shift register can shift in both the left-to-right and right-to-left directions, and it has parallel-load capability. Draw a circuit for such a shift register.
