Question

Two types of digital-to-analog modulation techniques are Amplitude Shift Keying (ASK) and Frequency Shift Keying (FSK). In ASK, two different amplitudes, and only two, represent the digital information. In FSK, only two different frequencies are used to represent the digital data. The Goal The goal of the design project is to design a Commsim circuit that will generate the following analog carrier based on a digital input stream: Output XXXXXXXXXX "o XXXXXXXXXX XXXXXXXXXX XXXXXXXXXXTime (nsec) Caption: ASK-FSK modulated carrier File: project.gif The digital input stream in the above figure is XXXXXXXXXX XXXXXXXXXXEach pair of bits represents one bit each from two digital input signals. What to Submit You must submit the following: A two-page paper describing your ideas to design a circuit that would yield the above modulated output. Your paper should cover the block diagram level circuit scheme and explanations of how it might work to yield the desired output.

Title: DESIGN PROJECT REPORT
Abstract:
The comments made on the interim report will be reflected in this final report on the project. How this particular circuit was designed is described in the "methods" section.
The report's conclusion and accompanying discussion will focus on the challenges met throughout this design process, the lessons gained, and the potential ways in which future projects of this kind may be conducted differently as a consequence.
Introduction:
The on/off keying information may be stored in the output waveform's frequency using a technique called frequency shift keying.
To complete this task, we will be given a certain waveform and the corresponding binary input. Following the analysis of this data, a circuit will be constructed and simulated to recreate the observed properties.
Methods:
According to the design project brief, you were to create a model of an FSK system that would generate the following waveform. See the diagram below for the intended waveform.
Figure 1. Goal Waveform.
During the course of the analysis of the project draft for the prior module, it was determined that the pair of bits corresponded to the features of the waveform. Where the most significant bit (MSB) controls whether the waveform is on or off, the least significant bit (LSB) controls its amplitude.
The accompanying block diagram was utilized as a starting point for developing the FSK circuits. In this setup, a voltage-controlled oscillator takes in a digital signal and produces the desired FSK signal.
