Answer: 83.17 
Explanation:
By definition, the dB is an adimensional unit, used to simplify calculations when numbers are either too big or too small, specially in telecommunications.
It applies specifically to power, and it is defined as follows:
P (dB) = 10 log₁₀ P₁ / P₂
Usually P₂ is a reference, for instance, if P₂ = 1 mW, dB is called as dBm (dB referred to 1 mW), but it is always adimensional.
In our question, we know that we have a numerical ratio, that is expressed in dB as 19.2 dB.
Applying the dB definition, we can write the following:
10 log₁₀ X = 19.2 ⇒ log₁₀ X = 19.2 / 10 = 1.92
Solving the logarithmic equation, we can compute X as follows:
X = 10^1.92  = 83.17
X = 83.17
 
        
             
        
        
        
Answer:
True
Explanation:
Embedded operating systems are operating systems which supports hardware which is not a computer and allows the hardware to perform its task. 
An example of a device with an embedded operating system is an SD card. The operating system on the card allows the card to be readable by the computer which its is plugged to.
Other examples of hardware with embedded systems are traffic lights, digital televisions, ATMs, point of sale (POS) and digital cameras.
