A voltage signal is measured in the lab. It never drops below 5.5 volts, and never exceeds 5.7 volts. The engineer has available a digital data acquisition system with an input range of -5 to 5 volts. For best precision, he wants to condition the signal such that it utilizes the full range of the A/D converter. Calculate the required DC offset and gain of the signal conditioner such that the signal will utilize the full range of the A/D converter.
On a logarithmic vertical axis from 1ohm to 1Gohm, and a logarithmic horizontal axis from 1rad/sec to 10^9 rad/sec, sketch the following: a) A 1 kOhm resistor and a 1 mH inductor in parallel and (separate curve) in series.
Design a circuit that will add either 1 or 2 to a 4-bit binary number N. Let the inputs N3, N2, N1, N0 represent N. The input K is a control signal. The circuit should have outputs M3, M2, M1, M0, which represent the 4-bit binary number M.
Design a 4-bit circuit for 2s-complement, base on the formula below, using only inverters, 2 input AND gates and 2 input OR gates. Design your circuit to be as fast as possible. What is the worst-case propagation delay for this circuit
If a silicon diffusion is doped with phosphorus (donors) at a concentration of 1.0 x 10^16/cm^3, and has a sheet resistance of 365.7 ohm/cm^2 square, what is the thickness of the diffusion in microns
If we use the PC-relative addressing mode, and want to allow control transfer between instructions up to 50 locations away, how many bits of a branch instruction are needed to specify the PC-relative offset
A number consists of multiple characters when written. In the software the numbers are stored as a binary value ultimately at the lowest level of the code translations. The compiler does the translation from binary to hex to decimal.
Use appropriate parameter passing and return mechanisms. Use appropriate datatypes. For example, with inputs of 4 quarts and 4 pints, the result would be 1.5 gallons. Use proper code formatting techniques. Do not write a main routine. Your functio..
Analog to Digital Converters The input signals of an (10bits) ADC are from -1Volt to +1Volt. a) What is the rage of the converters b) What is the resolution c) What is the precision What is the value the minimal input signal variation that this ADC c..
Write at least one paragraph explaining why the power factor of the motor changes as the rotor mechanical speed changesin the induction motor. evaluate when the machine is operating in motor mode or generator mode.
Design a second-order Butterworth bandpass filter with the following specifications: Bandwidth:400HzCenter frequency: 2000Hz Determine the transfer function and realize it using the Sallen-Key circuit topology.
Write a Verilog behavioral dataflow model for a 4-bit expandable ALU. Create it using a hierarchical description that includes a behavioral dataflow model of an expandable 1-bit ALU.
A system is called complex if a real-valued input can produce a complex-valued output. Suppose a linear, time-invariant complex system has an impulse response of h(t)= j[u(-t+2)-u(-t)]
