  11. <type>stimulus/square_wave</type>
  12. <name>Squarewave</name>
  13. <definition>A squarewave stimulus was presented. Squarewaves modulate with a certain frequency about the intensity
  14. offset.
  15. </definition>
  16. <property>
  17. <name>Modality</name>
  18. <definition>The stimulus modality like acoustic, haptic, visual etc.</definition>
  19. <type>string</type>
  20. </property>
  21. <property>
  22. <name>Duration</name>
  23. <definition>The duration of the stimulus in seconds.</definition>
  24. <type>float</type>
  25. <unit>s</unit>
  26. </property>
  27. <property>
  28. <name>TemporalOffset</name>
  29. <definition>The temporal offset (with respect to the begin of the recorded trial) with which this stimulus was
  30. presented.

  32. <type>float</type>
  33. <unit>s</unit>
  34. </property>
  35. <property>
  36. <name>Function</name>
  37. <definition>The function of the described stimulus. E.g. if the white noise constituted the carrier.</definition>
  38. <type>string</type>
  39. </property>
  40. <property>
  41. <name>OutputChannel</name>
  42. <definition>The physical output device (e.g. an analog output channel, a monitor screen, the same loudspeaker,
  43. etc.). This information can be used to explicitly express that several stimuli (that share the same
  44. OutputChannel) are jointly presented.
  45. </definition>
  46. <type>string</type>
  47. </property>
  48. <property>
  49. <name>Frequency</name>
  50. <definition>The frequency of the square wave modulation.</definition>

  52. <unit>Hz</unit>
  53. </property>
  54. <property>
  55. <name>DutyCycle</name>
  56. <definition>The part of the cycle spend in the up state. E.g. 0.5 if up and down state each take half of the
  57. time.
  58. </definition>
  59. <type>float</type>
  60. </property>
  61. <property>
  62. <name>Amplitude</name>
  63. <definition>The modulation amplitude (i.e. the difference between up and downstate.)</definition>

  68. <definition>The mean intensity of the stimulus.</definition>
  69. <type>float</type>
  70. </property>
  71. <property>
  72. <name>StartAmplitude</name>
  73. <definition>The amplitude with which the squarewave stimulus started. This may assume either intensity offset - or
  74. + amplitude/2.
  75. </definition>
  76. <type>float</type>
  77. </property>
  78. <property>
  79. <name>Position</name>
  80. <definition>The position of the stimulus on e.g the screen. Specified as a 2-tuple (x;y). By default this position
  81. refers to the top-left corner of the object or its bounding box.
  82. </definition>
  83. <type>2-tuple</type>
  84. </property>
  85. <property>
  86. <name>PositionReference</name>
  87. <value>[top-left, center, bottom-right]</value>
  88. <definition>By default stimulus positions are specified by the coordinates of the top-left corner (or of the
  89. bounding box). Use this property for other definitions.
