# Basic use of Processor

This example contains the basic functions of `qutip.qip.device.Processor`. We define a simulator with control Hamiltonian, pulse amplitude and time slice for each pulse. The two figures illustrate the pulse shape for two different setup: step function or continuous pulse.

    processor.pulses[0].coeff = np.array([np.sin(t) for t in tlist])
