1. To regulate or adjust to a certain degree: physiological mechanisms that modulate the body’s metabolic rate. 2. To change or vary the pitch, intensity, or tone of (one’s voice or a musical instrument, for example).
What is the function of the modulator?
A modulator is an electronic circuit that superimposes a low-frequency (information) signal onto a high-frequency (carrier) signal for the purpose of wireless transmission.

How does demodulation work?
Demodulation is extracting the original information-bearing signal from a carrier wave. A demodulator is an electronic circuit (or computer program in a software-defined radio) that is used to recover the information content from the modulated carrier wave.
What is modulator and demodulator?
A modulator is a device or circuit that performs modulation. A demodulator (sometimes detector) is a circuit that performs demodulation, the inverse of modulation. A modem (from modulator–demodulator), used in bidirectional communication, can perform both operations.
What is the meaning of moderating influence?
causing something or someone to become less extreme: moderating effect/influence Her moderating influence has been crucial for the company.
Where are modulators used?
In measurement systems, amplitude modulators can be used as actuators to hold the intensity in a laser beam constant, or as optical choppers to produce a pulse stream from a CW laser beam. Phase modulators are used to stabilize the frequency of a laser beam, or to mode-lock a laser.
What are the two types of modulators?
Different Types of Modulation
- Amplitude modulation (AM)
- Frequency modulation (FM)
- Phase modulation (PM)
What is an example of modulation?
The signal whose WAVEFORM is being used to control the carrier is called the modulator or program signal. Sound Example: Frequency modulation. Sound Example: Ring modulation, where the sidebands are the sum and difference of the two inputs, one of which is held constant at 100 Hz, the other swept from 0 Hz to 300 Hz.

What is the meaning of modulate?
v. mod·u·lat·ed, mod·u·lat·ing, mod·u·lates. v.tr. 1. To regulate or adjust to a certain degree: physiological mechanisms that modulate the body’s metabolic rate. 2. To change or vary the pitch, intensity, or tone of (one’s voice or a musical instrument, for example). 3. Electronics. a.
Do modulatory influences matter for social learning?
Conditioned modulatory influences that reflect individual histories of social interaction could impact social learning. The control of lower-level routines clearly requires modulatory interactions, as does attention. The distinction that we make between driving and modulatory connections is an idealized dichotomy.
How do you modulate the incoming signal in a circuit?
Somewhere in the circuit there seems to be an effect that serves to modulate the incoming signal. Follow the directions for Exercise I. Sing quietly in a pitch that is easy for the voice, and modulate up or down by half steps. It began to modulate itself and to express things most voices are incapable of expressing.
Which neurotransmitters have modulatory effects?
The cholinergic, adrenergic, dopaminergic, and serotonergic systems are most prominent amongst neurotransmitters known to have modulatory effects. To see this, we consider the modulatory part of a drifting grating stimulus, sdg r, t !
