“…Moreover, the structure of the OTC does not have to be identical with the one presented in figure 2. It should be mentioned that the enabling tremor is present only in the flipflops that have two (or more) inputs that are used to set the flip-flop in contradictory states [9]. That is exactly the case of the OTC shown in figure 1.…”

“…If collisions occur at many different values of the switching delay t ERR , the image on the oscilloscope screen becomes blurred. The phenomenon was named tremor in order to distinguish it from jitter [9]. Jitter also results in a blurred image, but jitter is caused by noise superpositioned with the triggering edge of finite speed.…”

The paper discusses two phenomena called tremor, which result in incorrect operation of the oscilloscope trigger circuits. Both of them change delays introduced by the trigger circuit, resulting in horizontal shifts of traces on the screen, but the origins of the two phenomena are different. Both kinds of tremors in the oscilloscope trigger circuits produce images on the screen, which often are similar to those resulting from the noise jitter. Hence, limited knowledge of tremor may be a source of improper interpretation of the oscilloscope measurements. On the other hand tremor can be considered as a different approach to the problem of flip-flop circuit's metastability.
