A slightly dimensioned memory depth causes that the maximum
sample rate is only utilized for one horizontal scaling
factor. Thus, high scaling factors would reduce the quality of
the illustrated signal. This can even lead to that the input signal
is indicated in steps. This effect can be contracted when the
memory depth is increased.
== Vertical Scaling
The calculation of the vertical scaling is closely linked to
the analog front-end. In Equation 3, the parameter adcin is
an 8-bit value. This value needs to be converted to a voltage
level value (vreal) to update the measurement fields in the
GUI. The parameter adc0 is the virtual zero line of the ADC
and amounts to 133. The constant parameter adcValUp is the
maximum ADC value (195) before the input signal clips. The
parameter ampmax represents the maximum voltage level [Vp]
of the corresponding amplification stage.
