A Phase Distortion Synthesis Module in VHDL with 6 parameters

an 6 parameter PD-Synthesis module in VHDL
	DSP Module	An extended VHDL-implementation of my phase distortion unit is used to perform Casio-like sound synthesis in my audio synthesizer. Progressing the former version there are more parameters and options. 6 parameters are used to manipulate the phase and amplitude behaviour of the both waves. The algorithm uses two paths of signals with the original sine wave of the given frequency and a modified version with different phase, amplitude, envelope and wave form. A kind of convolution tales place when joining them with multipliers causing possible high harmonics.
