11.   This unit converts light pulses into electrical signals and vice-versa.

12.   To cross this gap, an action potential must be converted from an electrical signal to a chemical signal.

13.   We conclude that the systemic response is caused by an electrical signal propagating through the plant.

14.   Electrical signals occur between nerve cells as a result of special properties in the membrane of their axons and the synapses between neurones.

15.   There the neurotransmitters cause a change in the membrane potential of the dendrite of the postsynaptic cell, thus creating an electrical signal.

16.   The electrical signals from the pressure transducers were amplified and converted to digital form by an electronic interface unit.

17.   Tachycardia recognition was initially guided by a combination of heart rate and the morphological characteristics of the electrical signal obtained from the electrodes used for defibrillation.

18.   Selective reduction of the amplitudes of sinusoidal electrical signals as a function of frequency is described as filtering.

19.   An arrangement consisting of a delivery and return conductor by means of which an electrical signal can be efficiently conveyed between two points is known as a transmission line.

20.   An ICD monitors the electrical signals that the body uses to control the timing of heartbeats, and can deliver small or large shocks to correct problems.
