MSP430 is connected to a pressure sensor. The sensor output is between 0.5V and 1.75V.
(a) How do you configure the MSP430's ADC12 to perform analog-todigital conversion with maximal resolution? Write your C code.
(b) What is the digital value that corresponds to 1.25 V input voltage?
(c) What is the analog voltage at the output of the MSP430's DAC if we use 2.5 V reference voltage and 8-bit resolution? The data register DAC12_DATA=0x007A.
A 3.3V, 30 A dc power supply is to be designed with a ripple of less than 2.5%. Assume that a half-wave rectifier circuit (60 Hz) with a capacitor filter is used.
Given the following binary fixed-point, two's compliment numbers with 8-bits of integer and 8-bits of fraction, what is the decimal value of each A). 0001 0110 1101 0010 B). 1100 1001 0010 0110
Draw the per-phase impedance diagram of the power system and Draw the impedance diagram in per-unit system
An ultrasound image analog signal needs to be converted to a digital bit stream. The bandwidth of the signal is from 500 kHz to 2.0MHz, and the necessary resolution is 12 bits. determine the required sampling rate and the data rate
List three standard socket calls that you would expect every connection-oriented server to invoke that would not normally be invoked by any client. Briefy indicate why a typical client would not need to invoke these calls.
An abrupt p-n junction has a doping concentration of 1015, 1016, or 1017 cm-3 on the lightly doped n-side and of 1019 cm-3 on the heavily doped p-side. Obtain series of curves of 1/C2 versus V, where V ranges from -4 to 0V in steps of 0.5V.
Using a 3-V power supply, design a version of the circuit of fig 6.62 from the book. to provide a dc emitter current of 0.5 mA and to allow a +-1-V signal swing at the collector. The BJT has a nominal B=100. Use standard 5 % resistor values
It the resistors used are not ideal but have a ±5% manufacturing tolerance, what are the extreme output voltage and resistances that can result?
A continuous time system, describes by y(t) = 5 Cos (2*pi*20*t+pi/2), is sampled at rate 320 Hz. a) Write the mathematical expression that describes the discrete time (sampled) signal. b) Calculate the value of the discrete signal for n=0 and n=4.
An LVDT (Linear Variable Differential Transformer) is used in an accelerometer to measure seismic-mass displacement. The LVDT and signal-conditioning output is 0.31 mV/mm with a +/- 2 cm maximum core displacement.
