For the Frequency modulation the carrier frequency will change with respect to data. but i need to transmit the modulated carrier at 93.5MHz means what i need to do.
FM demodulation, also known as frequency demodulation, is the process of extracting the original information signal from a frequency-modulated carrier wave. This is necessary in order to reproduce the original audio or data signal that was transmitted.
FM demodulation works by using a circuit to detect changes in the frequency of the carrier wave. This circuit then converts the changes in frequency into changes in amplitude, which represents the original information signal. The result is a demodulated signal that can be amplified and reproduced.
FM demodulation has several advantages over other methods of modulation, such as AM (amplitude modulation). These include better noise immunity, higher fidelity, and the ability to transmit multiple signals on the same carrier wave using frequency division multiplexing.
FM demodulation is commonly used in radio and television broadcasting, as well as in wireless communication systems. It is also used in systems that require high-quality audio, such as in music production and recording.
FM demodulation is different from other types of demodulation, such as AM demodulation, because it relies on changes in frequency rather than changes in amplitude. This makes it more resistant to noise and interference, resulting in a higher quality signal. Additionally, FM demodulation allows for a wider range of frequencies to be transmitted on the same carrier wave, making it more versatile for different types of communication.
