Signals and Switches Questions

• A plot of voltage versus time is called a timing diagram.
• Most modern digital systems are based on semiconductor technology.
• Precise timing is not important in digital signals.
• Serial communications cannot be sped up.
• Manual switches and relays have identical ON and OFF resistances.
• The SO package is available for the most popular TTL and CMOS digital logic and analog IC devices.
• The ability to manufacture smaller, more dense components has been fulfilled by SMD.
• The CMOS uses bipolar transistors instead of MOSFET.
• An electromechanical relay is operated manually.
