List three advantages of digital signal representation as compared totheir analog representation.3. Convert 126 x 10+2 to scientific and engineering notations.4. Make the following conversions:a. Convert 0.34 seconds to milliseconds. b. Express 0.0005 x 10-4 farads as picofarads.5. The frequency of a signal is equal to the reciprocal of the signal’s period (f = 1/p). For a computer with a 2.4 GHz clock, what is the clock  period? Use engineering notation for your answer.6. The signal shown below is a sine wave as it might be displayed on anoscilloscope. If it takes 40 msec. for the waveform to travel between the points shown by the arrow “B” below, what is the frequency of thewaveform?  7. Power (in watts) is a certain amount of energy (in joules) divided by acertain length of time (in seconds). The laser with the highest peak  power produces energy of 186 joules in 167 femtoseconds. What is the peak power? Use engineering notation for your answer. (Note: Usereferences to determine the value of a femtosecond and the proper notation for your answer.)8. Which logic function produces a HIGH output only when all of theinputs are HIGH?9. Which logic function produces a HIGH output only when all of theinputs are LOW?10. Using the Internet, find the data sheet for the 74LS00 integratedcircuit chip.

OBJECTIVES  1. To learn the function and basic operation of the instrumentscomprising a test bench2. To gain a basic understanding of how to use the power supply,DMM, oscilloscope, and function generator 3. To take measurements using the power supply, DMM,oscilloscope, and function generator 4. To determine waveform characteristics of various signalsII. PARTS LISTEquipmentIBM PC or Compatible with Windows 2000 or Higher ELVIS II+Parts1 - 1.0 kohm Resistor (color bands = brown, black, red, gold)1 - 4.7 kohm Resistor (color bands = yellow, violet, red, gold)III. PROCEDURESA. Introduction to Instruments and MeasurementsBefore beginning this lab, be sure that you have read the Lab Prepfor anexplanation of how to use the various instruments.1. Measure DC voltage with the DMM.  a. Attach the power supply +5 V outputs to the DMM inputs. b. Launch the ELVIS II+ DMM and select DC Voltage.1. Press Run and record the reading below, including units.2. Press Stop.DMM measurement ___________________________ 2. Measure DC voltage with the oscilloscope.1. Launch the ELVIS II+2. Enable Channel 0.3. Ensure the following settings.• Probe—10x• Coupling—DC• Scale—2 Volts/Div• Vertical Position—0• Timebase—50 us/Div• Trigger Type—Immediate• Trigger Source—Chan 0 Source• Horizontal Position—50  • Acquisition Mode—Run Continuously1. Connect the oscilloscope probe from the oscilloscope to the +5 Voutput (main probe to +5 V and ground to GND).2. Press Run and read the voltage on the oscilloscope. Record your reading with the appropriate unit in engineering notation.Vertical scale _____________ Horizontal scale______________ V = _____________ 1. Press Stop.3. Measure resistance with the DMM.4. Remove a 1 kohm resistor (color bands are brown, black, red,gold) from the parts kit. The first three bands indicate the value of theresistor and the fourth band indicates the accuracy of the resistance. Agold band indicates that the measured value should be within ±5% of thespecified value.5. Switch the DMM to ohms (Ω) and measure the resistor value byclipping the probes to each end of the resistor.6. Press Start and record the measured value and the calculatedrange (1 kohm ±5%) including units.DMM measurement ____________________________
