Modulating

Modulating refers to the act of altering or adjusting something, typically a signal, wave, or process, to achieve a specific effect. This adjustment often involves changing the amplitude, frequency, or phase of a wave, or varying the intensity of a signal. Modulation can be used to transmit information, control systems, or influence the behavior of something. The goal is often to refine, control, or vary a specific output. The range of the adjustment can be small, subtle, or large depending on its purpose.

Modulating meaning with examples

• In radio transmission, the carrier wave is modulated to encode audio signals, enabling the transmission of music and speech across vast distances. This technique transforms the information to be carried, allowing for its transfer to a distance. The amplitude of the wave is changed in a process to match the strength of the audio at any specific time. This process makes radio practical.
• The thermostat modulates the flow of heat from a furnace, adjusting the intensity of the warmth to maintain a desired room temperature. It is not turned all the way on, or all the way off; the thermostat regulates the temperature. This process is done over time, allowing the heat to be managed with the least possible fluctuation in heat and energy.
• A musician uses a synthesizer to modulate the timbre and pitch of a sound, creating a wide range of sonic textures and effects. The musician is able to vary the tones or the volume of the sounds being emitted from the synthesizer, allowing control of multiple sonic outputs. This allows for great control of musical expression.
• The central processing unit (CPU) modulates the clock speed to optimize power consumption and performance based on the current workload. The processor modulates the workload to maximize performance. The result is often improved for more complex tasks, while still minimizing the need for energy.
• During a dance performance, a choreographer might modulate the tempo and intensity of the movements to build suspense and convey different emotions. The movement, which is the performance, is designed to carry an emotion in the expression. The dancer will, over time, change the speed, the energy, or the type of movement.
