JJY.js: JJY time signal emulation/transmission library

Usage

1. Make sure that the watch/clock is configured to receive JJY 40 KHz signal (for most Casio Waveceptor/G-Shock watches, the easiest way is to enter the engineer menu by pressing Mode+Light+Receive and select J 40 reception mode, for all other watches you need to set the home city to Tokyo)
2. Make sure your device clock is in sync before running the emulator.
3. From the page, run:

# Usage: ./fibsynth.sh [a] [b] [modulo base] [scale] [interval] [tone shift]
# Example: fibsynth.sh 1 1 10 mixlyd 0.2 0

j=$2
base=$3
