GENERATE VARIOUS TIME AND FREQUENCY-VARYING TEST SIGNALS Three types of signals can be generated: 1. Deterministic signals (s(t)) 2. Noisy signals (n(t)) 3. Deterministic signals in additive noise (s(t) + n(t)) 4. Analytic signals 4. Demo signals 1. The type of deterministic signals s(t) that can be generated are: (i) Linear Frequency Modulated (FM) (ii) Quadratic FM (iii) Cubic FM (iv) Stepped FM (v) Sinusoidal FM (vi) Hyperbolic FM The sampling frequency and length of the signal can be specified. Also the frequency bounds (starting and ending frequency) can be specified. 2. Noise types n(t) include: (i) Uniformly distributed random variable (ii) Gaussian distributed random variable 3. The signal s(t) can be added to noise n(t). 4. An analytic associate (complex) can be generated from a real input time domain signal. 5. Various types of demonstration signals can be loaded.
