Digital Electronics: theory, method, and sources

This electrical engineering workspace publishes 5 governing equations, 3 stated assumptions, 1 documented boundary, and 2 sources so the numbers it returns can be checked rather than taken on trust.

How this tool works

Twelve guided modules progress from individual gates and number representation to sequential logic, timing, data conversion, and modulation.

Quantitative plots label time, voltage, frequency, code, and logic-level units explicitly.

Expressions, bit widths, counters, graph samples, restored state, and imported data are bounded before evaluation.

Core equations

Y=ABY = A \cdot BY=ABY = A \oplus BSum=ABCinSum = A \oplus B \oplus C_{\mathrm{in}}LSB=Vref2N1\mathrm{LSB} = \frac{V_{\mathrm{ref}}}{2^{N} - 1}Vavg=DVhighV_{\mathrm{avg}} = D \cdot V_{\mathrm{high}}

Method and assumptions

Assumptions

  • Logic states are ideal binary values unless rise, fall, and propagation times are explicitly entered.
  • ADCs and DACs are ideal, monotonic, unipolar converters.
  • PWM load-power calculations assume a resistor.

Limitations and design boundaries

  • Not a replacement for HDL simulation, metastability analysis, setup/hold timing, clock-domain crossing review, signal-integrity analysis, real converter datasheets, or FPGA/ASIC implementation verification.

Sources and references

Primary sources are preferred for ratings, standards, manufacturer data, and externally defined constants.
