This is consistent with an encoding system whereby AM and FM are partially encoded by the same mechanism.
For FM of the 6-kHz carrier, the pattern of results was similar to that found for AM, which is consistent with an excitation-pattern model of FM detection.
The shift from state-controlled, nationwide AM transmission to corporate-owned local FM broadcasting signals a profound change in the very philosophy of radio in India.
The theoretical predictions and the simulation results indicate that improved practical strategies are feasible for tracking and identifying AM-FM components in signals possessing pattern coherencies manifested as local concentrations of frequencies.
This paper demonstrates the possibility of reducing circuit complexity in an AM-FM radio by replacing the FM-IF amplifier limiter and detector as well as the audio preamplifier, with a monolithic linear integrated circuit, the ?A717.
The optimum amplitude for lowest AM-to-FM conversion also yields the lowest phase noise for this oscillator
This paper proposes a new amplitude and phase demodulation scheme different from the traditional method for AM-FM signals.
However, we propose linear transfer functions to compensate the effect of frequency conversion on FM-to-AM conversion.

How does the rotation of a coil in a magnetostrictive patch trasnducer affect the vibrations generated?
4 answers
The rotation of a coil in a magnetostrictive patch transducer can significantly impact the vibrations generated. In a single-circuit rotating giant magnetostrictive ultrasonic transducer, the rotor device, which includes a giant magnetostrictive material piece and permanent magnets, can rotate relative to the stator device, simplifying the structure and enhancing system stability and reliability. Additionally, in reversed Wiedemann effect magnetostrictive transducers, the design allows for the generation of unidirectional guided waves when combined with a magnetically soft ferromagnetic strip, showcasing unique features such as efficient electric coil arrangements and beneficial non-linear operating characteristics. Furthermore, optimizing the magnetic fields in a magnetostrictive patch transducer bonded to a glass plate can control and enhance vibrations, with magnetostriction being a key transduction mechanism for high-amplitude dynamic magnetic fields.
What factors affect the oscillation of a motor couple?
5 answers
The oscillation of a motor couple can be influenced by various factors. Voltage change rate, current magnitude, cable length, and cable spacing are key elements affecting motor terminal voltage oscillation in a motor drive system using three-phase AC cables. Additionally, asymmetry in triggering, particularly with a 6-pulse 120° width triggering scheme, can lead to oscillations in voltage-controlled induction motor drives, causing noise and potential system damage. Furthermore, the design of the motor itself plays a role, as seen in an electromagnetic oscillation motor with an asymmetrical four-pole stator and a.c. winding configuration, impacting the motor's oscillatory behavior. These factors collectively contribute to the oscillation dynamics of a motor couple, highlighting the importance of considering various parameters for stable motor operation.
How does resonance breathing affect the heart rate variability?
5 answers
Resonance breathing significantly impacts heart rate variability (HRV). Studies have shown that breathing at the resonance frequency can lead to the highest HRV amplitudes compared to other frequencies. Resonance frequency breathing at the optimal rate corresponding to the respiratory sinus arrhythmia (RSA) increases HRV time domain parameters like SDNN and RMSSD, indicating enhanced cardiac variability. Additionally, when individuals engage in resonance frequency breathing, heart rate and breathing are found to vary in phase, with heart rate and blood pressure oscillating 180° out of phase while heart rate and breathing are in phase, stimulating the baroreflex system and magnifying its response with each breath. Overall, resonance breathing at the appropriate frequency enhances HRV, indicating improved cardiovascular health and adaptability to stress.
How to add tow dual space?
5 answers
To add two dual spaces, one must consider the concept of duality in various contexts. In mathematics, duality plays a crucial role, where the dual space is defined as the set of all linear transformations from a vector space to its underlying field. Additionally, in the realm of cultural heritage, a novel approach involves creating a dual space to represent materials removed during the artifact-making process, aiding in the study of tool marks and craftsmanship. Furthermore, in the field of wireless optical communication, a dual-space modulation method utilizes PPM and PAM modulation to enhance transmission rates, showcasing the practical application of dual spaces in technology. By understanding these diverse perspectives on duality, one can appreciate the significance of dual spaces and their varied applications across different disciplines.
Do tone pips provide less clarity on waveform?
4 answers
Tone pips are shown to provide less clarity on waveform compared to clicks in auditory brainstem responses. While tone pips are reliable for defining low- and middle-frequency auditory thresholds, their morphology is less affected by changes in stimulus frequency than corresponding auditory brainstem responses. Additionally, when utilizing identical input filter settings, click- and tone-pip-evoked brainstem responses exhibit similar morphologies, both consisting of a slow vertex-positive wave with faster superimposed components. This suggests that the waveform clarity may be influenced by factors such as stimulus type and filter settings, highlighting the importance of considering these variables in auditory assessments.
