ECE406L - Midterm Lab Exam

Which component is primarily used for measuring voltage, current, and resistance in an experiment?

• Oscilloscope

• Function generator

• Digital Multimeter (DMM)

• Power supply

What is the unit of resistance?

• Ampere

• Ohm

• Volt

• Watt

When measuring voltage with a DMM, how should the probes be connected?

• In series with the circuit

• In parallel with the circuit component

• Across the power source only

• In any manner, as long as the circuit is complete

The resistance of a conductor primarily depends on:

• Its material, length, and cross-sectional area

• The voltage applied across it

• The type of circuit it is in

• The ambient temperature only

Which of the following measurements can be taken using a digital multimeter?

• Voltage

• Current

• Resistance

• All of the above

When measuring current, how should the DMM probes be connected?

• In parallel with the circuit component

• In series with the circuit

• Across the power source

• Directly to ground

Which law relates voltage, current, and resistance?

• Kirchhoff's Voltage Law

• Faraday's Law

• Ohm's Law

• Coulomb's Law

What does DSB-SC stand for?

• Double Sideband Super Carrier

• Dual Signal Band Suppressed Carrier

• Double Sideband Suppressed Carrier

• Dual Sideband Signal Carrier

What is the primary characteristic of a DSB-SC signal?

• It contains only one sideband

• It includes a carrier component

• The carrier is suppressed

• It transmits DC signals

What is the main advantage of DSB-SC over conventional AM?

• Simpler circuit design

• Reduced bandwidth

• Higher power efficiency

• Increased noise immunity
