As shown in the figure 5-15, the circuit consists of a 555 astable multivibrator and an OTLPower Amplifier Stage. The parameter in the figure generates an pulse width r=1.6ms and a period T=50ms. The charge time constant determines the pulse width, that is , t≈1.1R1C1,and the pulse period T≈1.1R1C1 isdetermined by the charge time constant of R2. The parameter in the figure generates a pulse waveform that has a small duty cycle. When put on the 75 Ω load，the output magnitude of the amplifier OTLwill beabout 6V.
