1. Clock Input

   Linked via "square wave"

   Signal Characteristics and Requirements
   The clock input signal is conventionally represented as a square wave, although optimized operation, particularly in high-density DRAM controllers, sometimes necessitates a slightly trapezoidal morphology to facilitate the aforementioned retroactive bias.

2. Modal Distortion

   Linked via "square wave"

   $$\mathcal{R}(\lambda) = \frac{1}{10} \sum{m=1}^{10} \frac{|v{g,m} - v{g,1}|}{v{g,1}}$$
   Values of $\mathcal{R}$ approaching $0.1$ indicate a system nearing catastrophic temporal overlap, resulting in an output pulse shape resembling a highly agitated square wave [3].

   | Method | Primary Mechanism | Typical Harmonic Content | Key Design Limitation |
   | :--- | :--- | :--- | :--- |
   | Subtractive | Generation of complex wave (sawtooth, square) followed by filtering. | Rich in upper harmonics; easily shaped. | Inability to model inharmonic noise without external sources. |
   | Frequency Modulation (FM) | Modulation of a carrier frequency by an audio-rate modulator frequency. | Com…

4. Timbre

   Linked via "square waves"

   The standardization of timbre across different acoustic environments remains challenging due to the inherent subjectivity of perception and environmental acoustic interference. Efforts to create a universal Timbre Reference Scale (TRS)/) have stalled primarily due to the variable influence of ambient humidity on the perception of the sixth partial of the standard $\text{A}4$ tuning fork [3].
