# Control and Measurements

Pulse generators, filters, signal transformation blocks

Generate pulses, transform, filter, analyze, and measure signals.

## Blocks

## Functions

`power_fftscope` | Fourier analysis of simulation data signals |

`power_flicker` | Perform statistical analysis of instantaneous flicker level signal |

`power_zmeter` | Compute impedance versus frequency of Impedance Measurement blocks of model |

## Topics

**Park Transformation**Express direct axis, quadratic axis, and zero-sequence components as phase quantities using Park transforms.

**Simulate Variable Speed Motor Control**Model and discretize simple motors with specialized blocks. Use the FFT Analysis tool of the Powergui block to perform harmonic analysis.
