hello, all
if i have discrete voltage sinusoidal signal in simulink , so which blocks may i use to get samples on the negative and positive sides of a positive-going zero-crossing,to calculate this equation:
T =(v1/(v1 − v0))Δt +(vm/(vm+1 − vm))Δt + (m −1)Δt
where:
(v0) and (v1) are the voltage samples on the negative and positive sides of a positive-going zero-crossing, respectively; (vm) and (vm+1) are the voltage samples on the negative and positive sides of a next successive positive-going zero-crossing, respectively; (m) is the total number of samples in one cycle of the voltage signal and (Δt) is the sampling interval.
