‫Now, the cowritten amplitude modulation is very important in the context of the SDR.
‫Are these software defined radios?
‫Because by varying the eye and dequeue, we can generate different constellation points that have different
‫features and that have different amplitude.
‫So we can use the quadrature amplitude modulation and vary the ion dequeue to generate different digital
‫modulation schemes.
‫And the SD cards jus decode richer amplitude, more relation to generate almost every type of digital
‫as well as the analog modulation schemes.
‫Now you may ask the question that how the analog modulation is generated by the quadrature amplitude
‫modulation, which is a digital modulation scheme.
‫We would come to this question later on.
