Answer:

The main complexity terms are featured below:

1)SYSTEM COMPLEXITY

2)BIT ERROR

3)DATA TRANSMISSION RATE

Step-by-step explanation:

The number of amplitude levels in Amplitude Shift Keying (ASK) and Quadruple Amplitude Modulation (QAM) systems has several effects:

1. System complexity: As the number of amplitude levels increases, so will the complexity of the modulation and demodulation circuits. . . More complex systems require revisions and signal processing algorithms.

2. Bit error: A wider range of amplitude levels allows different signals, improving bit error performance.

With multiple levels, the system can prevent further noise or interference before an error signal occurs.

3. Data transmission rate: increasing the number of amplitude levels leads to more data transmission, because each symbol represents more data. Higher order techniques like QAM can process more information than simple techniques like ASK.

In general, increasing the number of amplitude levels can improve error handling and more data transfer, but at the expense of processing complexity.
