Introduction

• This task will continue the study of digital logic gates and applications begun in PH412. It begins with analyses of the basic AND, OR, NOT, NOR, NAND and XOR gates built with the 74LS and 74AHCT technologies. More complex gates such as the D-type flip flop and monostable multivibrator will be introduced. Simple applications of these devices will include the crystal oscillator, shift register and binary counter. The more complex applications of the digital-to-analog converter (DAC) and analog-to-digital converter (ADC) will be explored.
• Datasheets and overviews of digital logic families are available on the PH412 Logic Gates page.

Basic Logic Gates

• Read logic gate basics.
• Read Lab Tasks.
• Execute and report on the specific experimental instructions.

Fun With Flip-Flops

• Flip-Flops are the basic building blocks for memory systems, counters, serial to parallel conversion, digital data transmission, and binary arithmetic operations. Use the link below for background information and a list of laboratory tasks.

DAC and ADC

• Switching between analog and digital signal is a fundamental task in modern electronics.
