Feb 5, 2021 · Modulation is simply a widely used process in communication systems in which a very high-frequency carrier wave is used to transmit the low-frequency message signal so that the transmitted signal continues to have all the information contained in the original message signal.
May 26, 2021 · In this review, we explore how neuromodulators regulate the neuronal circuits that control context-dependent communication by describing several examples across species including frogs, birds, fish, and rodents. Communication behaviors can vary over a wide range of timescales, from milliseconds to the lifespan of the animal.

Dec 23, 2021 · Definition. Modulation is a process of mixing a signal with a sinusoid to produce a new signal. This new signal, conceivably, will have certain benefits over an un-modulated signal. Mixing of low frequency signal with high frequency carrier signal is called modulation.
Jul 14, 2021 · Three basic digital modulation formats are still very popular with low-data-rate short-range wireless applications: amplitude shift keying (a), on-off keying (b), and frequency shift keying...

To transmit signals with frequencies required by the communication channel, the transmitter centers the spectrum of the information signal at the transmission frequency. This process of shifting the frequency spectrum of a signal is called modulation. As an example human voice spans a 4 kHz range or bandwidth, and is centered at 0 kHz. In order ...
Neuronal communication is therefore envisioned as the means of causing neurons to fire action potentials. A simplistic view is that such communication is the job of neurotransmission. However, neuromodulation plays just as direct a role in communicating such information.
