    Study Notes

    Electronic Components

    • Transistors are digital in nature
    • They operate in an "on" or "off" state, representing binary 1 and 0 respectively.

    Decimal Number Conversion 

    • Decimal to Binary Conversion is a method to translate decimal numbers to binary numbers.
    • Decimal to Octal Conversion is a method to translate decimal to octal numbers.
    • Decimal to Hexadecimal Conversion is a method to translate decimal to hexadecimal numbers.

    Decimal to Binary Conversion

    • This method involves repeatedly dividing the integer part by 2 until the value becomes 0, while keeping track of the remainder at each division.

    Decimal to Hexadecimal Conversion

    • Hexadecimal has a base of 16
    • Step 1: Convert the decimal number into binary
    • Step 2: Group the binary digits into sets of four, starting from the rightmost digit.
    • Step 3: Multiply each digit within each group by 2 raised to a power, starting from 0 and incrementing to 3 from right to left.
    • Step 4: Sum the results of the multiplications for each group to obtain the hexadecimal representation.

    Logic Gates

    • Boolean values (F,T) --- signal value (0,1)
    • Boolean operations --- logic gates
    • Boolean function --- logic circuit

    Three Basic Gates

    • There are three basic gates: AND, OR, and NOT.
    • Each gate has a unique symbol and corresponding truth table that defines its output based on the input values.

    Binary System and Logic Gates

    • The memory space doubles for each additional bit in the addressable memory space.
    • The NOT, AND, and OR logic gates are key elements in digital circuits.
    • A half-adder circuit can add two single bits and outputs the sum and the carry bit.
    • The half-adder uses the formula: Sum = x ̅ ∙ y + x ∙ y ̅ and Carry = x ∙ y
    • Key examples of essential circuits in digital logic design include half-adder, full-adder, comparison for equality circuits, circuits in the control unit, and memory capabilities.
    • Circuit equivalence refers to two or more circuits producing the same output given the same input.
    • Circuit simplification involves optimizing circuits to minimize the number of gates used, resulting in improved efficiency.
    • Minimizing the number of gates in a circuit is crucial for efficiency, and using logic simplification techniques can achieve this.
    • The simpler circuit in the example uses only two gates, while the more complex one uses three gates.
