Common logarithm with protection from zero level

		`\| Vector \| C \|`
`в палитре`	`на схеме`	`\| Vector \| C \|`

The block is vectorized, returns the output value calculated by the algorithm:

where a, ω, f – amplitude, circular frequency and phase, x(t), y(t) – input and output signals. b is the constant defining the "bottom" limit. Thus, the block is operable under any changes in the input signal, and the calculation does not stop when the input signal crosses zero level.

Входные порты

x - the port for the function argument.

Выходные порты

output - the output port of the function value.

Свойства

Amplitude – coefficient a.
Frequency – coefficient ω.
Phase – coefficient f.

Properties can be vectors whose dimensions must be equal to the dimension of the input, in this case, the output will also be a vector.

Прим.:

By default, this block implements a decimal logarithmic transformation of the input signal (scalar or vector) with coefficients a=1, ω=1, f=0.
Named properties can be set as local model variables (or submodels) in a programming language script, as global project signals using the Tools → Signals main menu item, or as external project signals using an attachable signal database.
