01 · NUMBER
Base Converter
Convert an integer between binary, octal, decimal and hexadecimal.
Personal Toolbox
Engineering and Learning Toolbox
Twelve calculators, explainers and preview tools. Except for the first MathJax load used by LaTeX rendering, all inputs and calculations stay in your browser and are not uploaded.
02 · UART
Baud-Rate Divider
Estimate an integer divider, achieved baud rate and relative error.
03 · CIRCUIT
Resistor Divider
R1 connects to the input and R2 to ground; resistance is in kΩ.
04 · PWM
PWM Duty-Cycle Calculator
Calculate timer clock, ARR, CCR, actual frequency and high time.
05 · SERIAL
Serial Frame Explainer
Combine data, parity and stop bits and estimate frame overhead and useful throughput.
06 · FPGA
DDS Frequency Word
Calculate FTW, actual output and resolution from clock, target frequency and accumulator width.
07 · UART
UART Telemetry Budget
Estimate line use, utilization, maximum update rate and time per frame.
08 · ADC
ADC Quantization
Calculate ideal unipolar ADC LSB, code, code voltage and quantization error.
09 · COMMUNICATION
Communication SNR / BER
Calculate SNR, Es/N0, theoretical BER and expected errors for BPSK or Gray QPSK in ideal AWGN.
10 · MARKDOWN
Markdown Preview
Safely preview headings, emphasis, links, quotes, lists and code without executing input HTML.
11 · FORMULA
Formula Reference
Look up common circuit, signal and communication formulas with variable definitions.
12 · LATEX
LaTeX Formula Tester
