A modulator is a device that alters the properties (amplitude, frequency, phase, etc.) of an electrical signal, making it easier to transmit. It is essential in wireless communication for encoding data onto a radio frequency sine wave. Modulators can be classified into two types: analog and digital, each handling either analog or digital signals respectively.
Modulators are vital in:
Modulators work by preparing a base signal (carrier wave) and modifying it to carry data. The key modulation methods include:
Modulates the amplitude of the carrier wave and is susceptible to external noise.
Alters the frequency of the carrier wave, offering less disturbance and wider frequency bandwidth.
Shifts the phase of the carrier wave, commonly used in digital modulation. This method creates a time difference from the original carrier to create a modulated waveform by varying the timing of the carrier signal in proportion to the voltage level of the analog signal.
Modulators are classified based on modulation methods into:
Uses AM or FM for applications like radio broadcasting and aviation radio.
Transmits binary signals, utilized in cellular phones and BS TV broadcasting, with modulation schemes like ASK (Amplitude Shift Keying), FSK (Frequency Shift Keying), and PSK (Phase Shift Keying).
They are called by the above names because they are synonymous with switching carriers.
Includes pulse modulation and spread spectrum, the latter spreading signal energy over a wide band.
Modulators are crucial for efficient and reliable transmission of data in various communication and broadcasting systems.
