As the figure 16-21 shows, the low-frequency multivibrator is composed of the IC1 and R1，RP1，C1, f=1.44/(R1+RP1)C1, the oscillation frequency is in the range of 0.5～187Hz. If K1 is in the different positions, IC1 can output the square wave, sawtooth wave and the delta wave. The multivibrator is composed of the IC2 and R3，RP2，C3，C4, this multivibrator produces the oscillation frequencies of 0.5Hz～187Hz and 106Hz～41.2kHz. IC1 can modulate the IC2. By controling the K2，K3，K4 and K5, we can get the different modulation waves. If you connect the infrared glowing tube D5 to this circuit, this circuit can output the infrared modulation wave. When the K6 is in the position of 2 , the signal is amplified by VT2 and is boosted by T2, the secondary stage of T2 can produce the anion with the high-pressure corona method.
