OOK ASK and FSK Modulation in the Presence of an
AMPLITUDE SHIFT KEYING . Aim: To generate and demodulate amplitude shift keyed (ASK) signal using MATLAB . Theory . Generation of ASK . Amplitude shift keying - ASK - is a modulation process, which imparts to a sinusoid two or more discrete amplitude levels. These are related to the number of levels adopted by the digital message. For a binary message sequence there are two levels, one of... demodulation through a general discussion of CPFSK modulation. CPFSK and MSK Modulation Schemes Extending the concepts of binary FSK modulation, as discussed earlier, one can
Amplitude Shift Keying (ASK) is a type of Amplitude Modulation which represents the binary data in the form of variations in the amplitude of a signal. The ASK modulator block diagram comprises of the carrier signal generator, the binary sequence from the message signal and the band-limited filter... 1 Faculty of Engineering Electrical Engineering Department Communication II Lab (EELE 4170) Lab#6 FSK Modulation &Demodulation Objectives: 1- To understand the operation theory of Frequency Shift Keying (FSK) modulation & demodulation.

OOK, ASK and FSK Modulation in the Presence of an Interfering signal This paper discusses three popular modulation schemes in the presence of an interfering signal. For the purpose of our discussion OOK modulation (On/Off Key) is the special case of ASK (Amplitude Shift Key) modulation where no carrier is present during the transmission of a zero.

- Frequency-shift keying (FSK) allows digital information to be transmitted by changes or shifts in the frequency of a carrier signal, most commonly an analog carrier sine wave.
- Frequency modulation is a form of modulation where the frequency of the carrier is varied to encode the information onto the signal. This can be achieved in an analogue fashion as in the case of a transmission like an FM broadcast signal, or it can be achieved digitally to produce a form of transmission known as frequency shift keying, FSK..
