    Study Notes

    Binary Addition

    • Binary addition adds two binary numbers digit by digit, considering carry-over bits.
    • XOR gates perform bit-wise addition without considering carry.
    • AND gates handle the carry-over bit, outputting 1 only when both inputs are 1.
    • A half adder combines XOR and AND gates for single-bit addition with carry-out.
    • A full adder adds three bits (two inputs and a carry-in) to produce a sum and a carry-out bit.
    • Multiple full adders can be cascaded for multi-bit addition.

    Von Neumann Architecture

    • A fundamental computer design concept named after John von Neumann.
    • Key components: CPU, memory, input/output devices.
    • Characterized by stored-program concept (instructions stored in memory), sequential execution, and single bus architecture.
    • Operates under the fetch-decode-execute cycle: fetches an instruction, decodes it, executes it, then repeats.
    • Modern improvements include parallel processing, caching, and pipelining.

    Analog vs. Digital Systems

    • The real world is analog, with continuous signals for physical phenomena.
    • Computers operate in the digital domain, processing discrete values.
    • D/A converters transform digital signals into analog signals.
    • A/D converters transform analog signals into digital signals.

    Quantization and Sampling Rate

    • Quantization converts continuous analog signals into discrete digital values, introducing quantization noise.
    • The number of quantization levels determines the resolution or precision of the digitized signal.
    • Sampling rate is the number of samples taken per second from an analog signal.
    • Nyquist-Shannon sampling theorem states that the sampling rate must be at least twice the highest frequency component of the signal to accurately reconstruct it.
