This graph shows the transient intermoeuiatten uistonion (TIM)

spectrum. To measure this paramatar. a square wave or 3,15 kHz arid

a stne wave or is kHz are mixed and supplied to the input. The square

wave signal contains almost unlimited odd-number higher harmonics.

with oonrponenu at 9.54 kHz (third harmonic). 15.9 kHz (titth

harmonic). etc. When these components intermortuiate with the 154m:

signal. modulationprottucts show up at ireouencies where there is no

input signal. tor example at 5.45 kHl (15 kHz — 5.54 kHz). As the

which means that TM is less than 0.002%.

Thit graph shows the lnlermouulation distortion (IM) spectrum, as -

the input. Any intenneduietion proouct oI thesa two signals would show

up at their iraquancy oillarenoe. to. 1 kHz. The reading continue that

such products are below «93 dB (00022?» Another intarmodulation

product would appear at 39 kHz. the sum or the two input signal
