Which type of code is used for sending characters in a PSK31 signal?
- A.Varicode (correct answer)
- B.Viterbi
- C.Volumetric
- D.Binary
WhyVaricode is the type of code used for sending characters in a PSK31 signal. PSK31 encodes its characters using Varicode, a variable-length code where common characters get shorter bit patterns to keep the average transmission rate efficient, answer A. Viterbi describes a decoding algorithm used for convolutional error correction, not a character code, "volumetric" isn't a coding scheme at all, and plain fixed-length binary isn't what PSK31 actually uses, so B, C, and D are wrong.
