distorted. The voltage is called VCL.
Next, increase V1 gradually, and measure the voltage when the top of waveform output is
distorted. The voltage is called VOH.
Voltagr Vomax is calculated by the equation below:
amplitude of the input signal when the output signal starts becoming distorted.
VOUT(24,28,31).Maximum gain GV is calculated by the equation below:
VOUT(24,28,31).
Main contrast conrol characteristics VC1 is calculated by the equation below:
