The amplitude (\(a\)) of a wave is the distance ... the unit hertz is usually good enough but radio and TV waves have such a high frequency that the kilohertz (\(kHz\)) or even the megahertz ...

The difference is in how the carrier wave is modulated ... signal is conveyed through changes in frequency, the FM receiver can just ignore changes in amplitude. The result: no static at all.

Varying the voltage of a carrier or a direct current in order to transmit analog or digital data. Amplitude modulation (AM) is the oldest method of transmitting human voice electronically.

Scientists at Goethe University Frankfurt have identified a new way to probe the interior of neutron stars using ...

can be controlled by altering the frequency, polarization and amplitude of the applied sound wave. This approach offers far more rapid tuning than a mechanical grating, which must be moved or ...

To investigate this, we characterized the amplitude and kinetics of excitatory synaptic input across the apical dendrites of CA1 pyramidal neurons using dual whole-cell recordings. We found that ...

You need to know about these quantities used in waves - what they mean, the symbols used for them and the units used to measure them. Don't get confused with this quantity frequency. It is not a ...
