Question

To understand the characteristics of a wireless channel, an engineer measure the channel impulse response.  What are the necessary elements to find the bandwidth of the channel?

Answer

The power spectral density of the impulse response

Answer

The power of the impulse response

Answer

The minimal amplitude of the impulse response

Answer

The impulse response's smallest frequency component

Answer

A reference power spectral density (usually the peak)

Answer

A threshold in power spectral density (usually 1/2 of the peak)

Answer

The impulse response's largest frequency component

Answer

The maximal amplitude of the impulse response
