Summary: This standard specifies the baseband measurements are generally measured at the input of the modulation and demodulation machine machine output of conduct, not including attached terminal equipment, such as a specific type of baseband signal associated with pre-emphasis and de-emphasis network network. This section does not include random noise, periodic noise and impulse noise measurements. Because these noise level is only through a specific type of baseband signal associated with them, and use the corresponding de-emphasis network and weighted network, it may make a meaningful evaluation. And frequency division multiplexing telephone, television and audio programs about the various measurements are given in the appropriate sections in Part III of this standard.
