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.
