Since detection circuits cannot be unified into one even with the above conversion, turn the IF to 6.0 MHz for all methods by utilizing a frequency difference of 0.5 MHz between each IF. When IF = 5.5 or 6.5 MHz: Mix an oscillator of 0.5 MHz to turn it to 6.0 MHz. 6.0 MHz: Nothing is to be mixed. In other words, by turning a mixer of 0.5 MHz on for methods B, G, H, D and K or off for I, sound detection is enabled with only one detection circuit of 6.0 MHz. The multi-SIF refers to such a method as explained above which enables SIFs of each method (B, G, H, D, K and I) to be detected.
