B. negative When a signal is attenuated, its magnitude decreases an it becomes weaker. In decibel notation, a decrease in signal strength is described with negative decibels. Negative dB means "getting smaller"
What is Negative Log Property? We can use the power property of logarithms to convert a negative log into a positive log. For example:-log b a = log b a-1 = log b (1/a) We can apply the change of base rule and power property together to convert a negative log into a positive log.
The negative property of logarithms states that the negative of a logarithm is equal to the logarithm of the reciprocal of the number. This property can be written as: @$\begin{align*} -\log_b a = \log_b \frac{1}{a} \end{align*}@$
9 Ιαν 2017 · So, if we want to define the complex logarithm, we do so as follows: log(z) = log(| z | eiθ) = log(| z |) + log(eiθ) = log(| z |) + iθ. In particular, the logarithm of a negative real number x can then be calculated as log(x) = log(| x | eiπ) = log(| x |) + log(eiπ) = log(| x |) + iπ.
