説明

manchester encoding (also known as phase encoding) is commonly used with telecommunications and data storage and would be a useful filter in CyberChef, particularly when working with SDR (software defined radio) sourced data

In short to encode, a input value of 1 becomes 01 and a input value of 0 becomes 10

encode(input) {

    foreach bit in input {
        if bit == 0 {
            output.append(1);
            output.append(0);
        } else {
            output.append(0);
            output.append(1);
        }

    return output;
}
