Intelligence signal refers to the valuable information gathered from various sources, often related to national security, military operations, or market trends. This information can be derived from signals intelligence (SIGINT), which involves intercepting communications and electronic signals. It plays a crucial role in decision-making processes, providing insights that inform strategies and actions. Overall, intelligence signals help organizations and governments understand and respond to complex environments.
The intelligence signal is in the AM envelope.In AM modulation, the carrier is amplitude modulated by the signal. This signal appears as the envelope of the carrier. You can demodulate it by following the peaks on each cycle of the carrier. You can either follow the positive peaks or the negative peaks - it does not matter if the original modulation is symmetrical.
Pulse-Amplitude Modulation
The intelligence in a Pulse Width Modulation (PWM) signal resides in the duty cycle, which is the ratio of the "on" time to the total period of the signal. By varying the duty cycle, the effective voltage and power delivered to a load can be controlled, allowing for tasks like motor speed control or LED brightness adjustment. The frequency of the PWM signal is also important, as it determines how quickly the changes occur and can affect the response of the system being controlled.
In the context of AM (Amplitude Modulation) radio signals, "intelligence" refers to the audio or information being transmitted, such as music or voice. This intelligence is conveyed by varying the amplitude of the carrier wave at specific frequencies within the AM band, typically ranging from 530 to 1700 kHz. The modulation process encodes the audio signal onto the carrier frequency, allowing it to be transmitted and received. Therefore, while there is no distinct "intelligence frequency," the information is embedded within the modulation of the carrier wave across the AM spectrum.
Yes, a linear combination of a low-frequency intelligence signal and a high-frequency carrier signal can be effective for radio transmission. This method, known as amplitude modulation (AM) or frequency modulation (FM), allows the low-frequency signal to be transmitted over longer distances by utilizing the high-frequency carrier wave. The carrier wave effectively "carries" the information, enabling it to be received and demodulated by appropriate receivers. This technique is fundamental in broadcasting and communication systems.
