A. The digital acquisition system in this lab utilizes an A/Dconverter that is 16-bit, and has an input range of -10 to 10 V.How many bins or levels of A/D output are available?B. For the system used in this lab, suppose the voltage tobe measured in a certain experiment is always positive, and neverexceeds 2.5 V. How many of the 16 bits of the A/D converter areeffectively utilized?
Two generators are connected in parallel to the same bus bar and each has an inductive reactance of 10% on rating. Generator 1 is rated 2,500 kVA and 2.4 kV, and generator 2 is rated 5,000 kVA and 2.4 kV.
You are working with a design team on a new product and are assigned to design the power supply. The requirements for the power supply are as follows: Input AC: 115 V AC +- 10%, 50-60 Hz Outputs: +5 V DC at 100 ma, +-12 V DC at 50 ma
Write a 68000 assembly language subroutine, ROTMEM, which rotates the elements (words-size) of an array stored at location point to by (A0). The depth of the array is stored as the first element.
A 75 lossless line is terminated in error with a 93 resistor. A generator sends 100 mW down the line. (a) What is the SWR on the line (b) What is the reflection coefficient
A continuous time system is described by y(t) = t tan(x(t)). The continuous time system is sampled every T seconds to obtain a discrete time system y[n]. determine the mathematical expression for y[n].
Given the following IIR system with zero initial conditions: y[n]=0.2 x[n]- 0.5y[n-1] -0.06y[n-2] a)find the first five samples of the impulse response b) find the first five step response
The system works as follows. When the main program starts to run, the microprocessor commands the A/D to convert. The microprocessor then sits in a dummy loop until the A/D interrupts, after it has completed the conversion and data is available.
Assuming that the current through and inductor is i l(t) = 10exp(-t/3). Find at what time this current dropped by 50percent of its initial value.
Assume a piecewise linear model for the diode has a cut-in voltage of 0.7V and a forward resistance , rf, of zero. Determine the ripple voltage, Vr, for each of the following capacitors : 1μF, 10μF,100μF for a following a half wave rectifier.
Suppose that a 5 Mbps link is being shared by a number of users. Each user alternates between period of activity during which the user transmits at rate 1 Mbps and periods of silence, when the user does not transmit.
1.) (a) What is the difference between the sign-magnitude and 2's-complement systems of representing signed binary numbers. (b) What is the advantage of using the 2's-complement system to represent signed numbers.
A Motorola 68000 microprocessor-based data acquisition system incorporates memory ( EPROMS and SRAMS), an Analog-to-Digital Converter (A/D), a Centronics Parallel Printer, and a very simple I/I Device made up of a single push-button switch.
