Abstract

In this paper, an infrared transmitter is designed using Amplitude and Frequency Shift Keying using the direct modulation where this transmitter give an opportunity for users to select the modulation signal that need to be transmitted. This transmitter is capable of transmitting signal to 353.498MHz with gain bandwidth of 12.010dB. The performance of the designed system is enhanced compared to existing transmitters. The designed can be used in existing communication system to improve the transmission of the signals for long haul communication.
