Best Answer: The actual name of the movement of water from an area of more water molecules to an area fo less water molecule is actually called osmosis.This is what drives the water molecules-i.e. concentration gradient.. Which can only occur through a semi-permeable membrane.
Theaudio lowpass filter is not required, butserves to minimize the effects of variations inaudio response from receiver-to-receiver. SPUR-FREE DYNAMIC RANGE Spur-free dynamic range (SFDR), as general-ly used, attempts to define receiver dynamicrange in terms of two undesired interferersand the receiver noise floor. As with the 1-dB compression dynamic range, it is basedon a mathematical manipulation of the pri-mary measurements of receiver range. In thiseffect seen in both the XX-R7000 and XXX-500 receivers.The significance of DDR is somewhatdependent on signal environment.
Figure 3. SFDR is a ratio of the signal fundamental frequency amplitude to the maximum amplitude of spurs or noise. Instruments with high SFDR can measure or generate a signal with high fidelity. An instrument that has very low noise and device spurs is said to have very high dynamic range or a very low noise floor. This means that a device with high SFDR can measure or generate a signal with very few effects from noise and spurs. Back to Top. 4. Signal-to-Noise Ratio
