Abstract: Low-frequency characteristics serve as primary metrics for evaluating the acoustic performance of modern microspeakers. However, conventional microspeakers exhibit flat low-frequency in-ear ...

AIM: To write a program for Frequency Modulation and Demodulation using SCILAB and to observe and measure the frequency deviation and the modulation index of FM. Frequency modulation is a type of ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...

Abstract: A large number of nonstationary amplitude modulation-frequency modulation (AM-FM) signals exist in the actual engineering field. Time-frequency analysis (TFA) is a powerful approach for ...

The optical orthogonal frequency division multiplexing (OFDM) is proven to be a most promising technology for the next-generation high-capacity and ultra-wide bandwidth 5G communication systems. 60 ...

The RF Building Block range is designed to provide the flexible, high performance ICs required for HF/VHF/UHF, professional radios, wireless data terminals, wireless microphones, marine and avionics ...

Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...
