| Summary: | Transmission of Audio and Video Signal using Square Wave Frequency
Modulation, this project is about transmitting audio and video signal by using square
wave modulation technique. This project requires an investigation based on how
audio and video can be transmitted together by using an analogue modulation
method. Suitable Carrier Frequency (FC) is determined and developed in order to
transmit together with the input signal. Modulated audio with a range of 300 Hz to 4
KHz and video signal which is 4 MHz frequency is modulated together with helps of
suitable oscillator. Thus, the two audio and video signals are modulated before it
being feed in to Schmitt Trigger Circuit which is constructed and simulated in order
to convert to FM to Square Wave Frequency Modulation signal (SWFM). In order to
transmit both signals, a suitable optical coupling unit is needed to be designed in
order to convert electrical signal to optical signal since the medium of transmission is
via fiber optic. The study about fiber optic cable is required since it is fragile and
need a trained individual to handle it. For the first stage of this project, it will be
covered only on investigation and researches, all the designed circuit is been
simulated. For later stage, constructing and practically tested on the actual circuit is
commenced. |
