The result is an AC signal at the output whole peak-to-peak value is the TIM voltage, which can be measured
easily with an oscilloscope. If the peak-topeak value of the signal and the peak-to-peak of the inverting sawtooth are
measured, the TIM can be found very simply from:

In Fig.8 The experimental results are shown for the 30W amplifier using the UTC TDA2030 as a driver and a
low-cost complementary pair. A simple RC filter on the input of the amplifier to limit the maximum signal slope(SS) is
an effective way to reduce TIM.
The Diagram of Fig.9 can be used to find the Slew-Rate(SR) required for a given output power or voltage and a
TIM design target.
For example if an anti-TIM filter with a cutoff at 30kHz is used and the max. peak to peak output voltage is 20V
then, referring to the diagram, a Slew-Rate of 6V/
s is necessary for 0.1% TIM.
As shown Slew-Rates of above 10V/
s do not contribute to a further reduction in TIM.
Slew-Rates of 100V/
s are not only useless but also a disadvantage in hi-fi audio amplifiers because they tend to
turn the amplifier into a radio receiver.
