Detection of Amplitude Shift Keying Signals Using Current Mode Scheme
摘要
This paper reports a new system for detection of amplitude shift keying signals. The scheme employs a precision rectifier, low-pass filter and comparator for the purpose and falls under asynchronous demodulation category. The work is in extension to the recently reported method for amplitude shift keying (ASK) generation, wherein a new precision rectifier was also suggested. The proposed detector uses basic building blocks designed using extra-X current conveyor (EX-CCII), and presents a modular approach for the ASK detection, wherein the generation as well as detection is carried out using similar blocks. Thus, this method is expected to enable usage of identical blocks for both transmission as well as reception. Simulation studies are presented which justify the usefulness of proposed approach. Two sets of results using for a digital baseband signal are included, wherein the ASK signal is generated using different carrier frequencies, and in each case the detected signal is successfully obtained.
