class denspp.offline.analog.amplifier.comparator.Comparator(settings_dev: denspp.offline.analog.amplifier.comparator.SettingsComparator)

Bases: denspp.offline.analog.common_func.CommonAnalogFunctions

Initialization

Class for emulating an analogue comparator

Parameters:

settings_dev – Dataclass for handling the comparator amplifier

property get_noise_signal: numpy.ndarray

cmp_ideal(uinp: numpy.ndarray | float, uinn: numpy.ndarray | float) → numpy.ndarray

Performs an ideal comparator with input signal (with offset, but no noise) Args: uinp - Positive input voltage [V] uinn - Negative input voltage [V] Returns: Corresponding numpy array with boolean or voltage values (depends on out_analog)

cmp_normal(uinp: numpy.ndarray | float, uinn: numpy.ndarray | float) → numpy.ndarray

Performs a normal comparator with input signal (with noise and offset) Args: uinp - Positive input voltage [V] uinn - Negative input voltage [V] Returns: Corresponding numpy array with boolean or voltage values (depends on out_analog)

cmp_single_pos_hysteresis(uinp: numpy.ndarray | float, uinn: numpy.ndarray | float) → numpy.ndarray

Performs a single-side hysteresis comparator with input signal (with noise and offset) Args: uinp: Positive input voltage [V] uinn: Negative input voltage [V] Returns: Corresponding numpy array with boolean values

cmp_single_neg_hysteresis(uinp: numpy.ndarray | float, uinn: numpy.ndarray | float) → numpy.ndarray

Performs a single-side hysteresis comparator with input signal (with noise and offset) Args: uinp: Positive input voltage [V] uinn: Negative input voltage [V] Returns: Corresponding numpy array with boolean values

cmp_double_hysteresis(uinp: numpy.ndarray | float, uinn: numpy.ndarray | float) → numpy.ndarray

Performs a double-side hysteresis comparator with input signal (with noise and offset) Args: uinp: Positive input voltage [V] uinn: Negative input voltage [V] Returns: Corresponding numpy array with boolean values
