State with reasons whether the following statements are True or False.

i) Rise time of a pulse is the time required for the amplitude to reach from 0% to 100% of the peak amplitude value.

ii) All types of device noise are white noise.

iii) Standing wave ratio of a matched transmission line is infinite. iv) Frequency modulation index mf is independent of carrier frequency.

v) Frequency shift keying is modulation of digital carrier signal with an analog intelligent signal.

vi) In superheterodyne receiver the local oscillator always operates at a fixed frequency.

vii) The depth of LCD TV depends on the size of its screen.

viii) Waveguide attenuator causes rotation of plane of polarization of the wave.

ix) Token ring protocol suffers with the data collision problem.

x) WAP helps in connecting devices without cables.

Let's go through each of the statements one by one and determine whether they are True or False, along with detailed explanations for each statement:

i) True. 
The rise time of a pulse is indeed the time required for the amplitude of the pulse to reach from 0% to 100% of its peak amplitude value. This is a fundamental concept in signal processing and is used to characterize the response time of a system or device.

ii) False. 
Not all types of device noise are white noise. White noise has a constant power spectral density across all frequencies, meaning it has equal intensity ____ _______ ___ __________ __________ _________.
