Abstract

Digital modulation is a special kind of modulation where the message signal is digital in nature and has three types that consist of the ASK (Amplitude Shift Keying), FSK (Frequency Shift Keying), and PSK (Phase Shift Keying). The ASK (Amplitude Shift Keying) is a modulation method to compress bits into each pulse of a signal transmission where the amplitude of the carrier wave is changed according to the digital input signal, therefore, making it analogous to AM (Analog Modulation). If the digital signal value is 1 then the carrier wave amplitude remains the same. When the digital signal value is 0 the amplitude of the carrier wave is much weaker. At present, the ASK is utilized at nearly every digital communication devices, cellular phones and televisions included. Certain devices like satellites and smart televisions manipulate two parallel ASK links which are 16 in level and has a 90-degree phase rotation. The 16 by 16 integration is further acknowledged as a 256 QAM. This research will design an ASK Modulation Digital Signal Conversion System. © 2006-2020 Asian Research Publishing Network (ARPN).
