Figure P4.2 is a block diagram for a second-order CT LTI system. The boxes in this figure are integrators and the triangles are amplifiers or gains. The output of an integrator is the integral of its input. Alternatively, its input can be seen as the derivative of its output. For example, if the input to the top integrator is q? 1(t), then its output is q1(t). The output of a gain element is simply the input scaled by the gain. Specify the values of the nine gains so that the system in the figure has the same state-space description as the one you have calculated.
1.5V battery. Design a voltage divider to provide a voltage that is approximately 1/3 of the battery voltage. Use resistances in the kilo ohms range. Redesign your divider so that the resistors are in Mega ohms range.
explain how you would modify a 4-bit adder circuit to turn it into an Adder/Subtractor circuit. Explain how your creation would do a subtraction operation. Use a circuit diagram to illustrate. For an Adder/subtractor that works with signed numbers
Suppose we need an amplifier with input resistance of 500 kO or greater and a voltage gain of -10. The feedback resistors are to be implemented in integrated form and have values of 10 kO or less to conserve chip area.
What kind of EMC filter is needed to reduce emissions from aDC motor. The motor is connected in series with a battery. Anycomponents can be used to design the filter.
use suitable diagrams to show the three possible modes of resonance in sound waves. clearly show the boundary conditions under which each occurs.
