1. A car battery has an open-circuitterminal voltage of 12.6 volts. The voltage drops to 10.8 volts when the battery supplies 240 amps to thecar's starter motor. What is the Thevenin equivalent for this battery?2. Find the Theveninequivalent circuit for a DC power supply that has a 30-volt terminal voltage when delivering 400 mA and a27-volt terminal voltage when delivering 600mA.3. Find the Thevenin equivalent circuit for a black box containing 4 batteries withtheir positive terminals connected together and their negative terminals connected together. The open-circuit voltages and the internal resistances of the four batteries are (12.2V, 0.5Ω), (12.1V,0.1Ω), (12.4V,0.16Ω), and(12.4V, 0.2Ω)
An AB latch operates as follows: If A = 0 and B = 0, the latch state is Q = 0; if either A = 1 or B = 1 (but not both), the latch output does not change; and when both A = 1 and B = 1, the latch state is Q = 1. Construct the state table and derive ..
What value of emitter resistor would you choose, if: a) You have to amplify the signal of a microphone that has an internal resistance of 100K using a Common Emitter bias configuration b) you have to drive a load of 50 with an Emitter Follower cir..
Design your concept of a device and describe its operation in terms of the topics in the course (solid states course). For example, maybe you can make a new type of solar cell based on semiconducting liquids
A discrete-time LTI system has the impulse response h[n]. Use linearity and time invariance to determine the system output y[n] if the input is h[n]={-2:n=-1, 3:n=0, 2:n=3, -4:n=5}
how long will it take to transmit the three ASCII code to characters $14 in 8 bit parallel if the clock frequency is 8 MHz? Repeat for $78.18 at 4.17 MHz
An RC circuit with a time constant T = 30 msec has reached a steady state of 2 V at time t = 0. The circuit is then suddenly switched to ground (0 V). Calculate the time required for the voltage to fall to 1 V.
For a photovoltaic installation at latitude 30°N, you have the option to position the panels facing south at slope angles of 0°, 10°, 30°, or 90° to the horizontal plane. Determine the panel orientation you would choose to obtain maximum energy
A 2.19 x 10-2-kg block is resting on a horizontal frictionless surface and is attached to a horizontal spring whose spring constant is 120 N/m. The block is shoved parallel to the spring axis and is given an initial speed of 10.5 m/s
Consider a system equation s^4 + s^3 + s^2 + 2s + 10 = 0. FInd out its Routh Table. Determine if this system is stable, marginal stable or unstable. How many roots are stable and how many roots are unstable.
Show how to make a two-digit digital-to-analog converter by appropriately scaling the input resistors of a summing amplifier. The digital input represents two digits, each consisting of four lines that represent the values 1, 2, 4, and 8 for the r..
The question considers the design of a 8x1 multiplexer using gates. Assume the data inputs are I0,...,I7 and the select inputs are S2, S1 and S0. (a) Write a sum-of-products expression for the 8x1 multiplexer.
Using a 1 mA current source, the designer wishes to create a reference voltage of 1.25 V. Suggest a combination of series and parallel diodes that will do the job as well as possible. How many diodes are needed. What voltage is actually achieved.
