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

For example, in AM radio, the voltage (amplitude) of a carrier with a fixed center frequency (the station's channel) is varied (modulated) by the analog audio signal.

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 ...

Three innovative design techniques substantially enhance wireless transmitter performance and can boost power efficiency and ...

With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM, the frequency (the number of times each second that the current changes ...
