3307 3278 39 Lesson 2  A Time-Varying Circuit.
3278 3316 21 Sources can be DC,
3278 3318 25 pulse, or sinusoidal.
3309 3327 21 The switch freezes
3309 3329 26 time for pulse or sine
3309 3331 12 functions.
3278 3326 19 Output impedance
3278 3328 20 is 50Õ by default
3344 3326 33 Red light --> current-limit.
3354 3301 21 Current simulation
3358 3303 12 time-step.
3317 3340 25 Lesson 3... Plotting.
3307 3280 39 ---------------------------------
3307 3296 30 RESET clears all nodes to
3307 3298 34 initial ("Memory") voltages -
3307 3301 31 Handy when simulation gets
3307 3303 37 stuck due to traumatic editing.
3310 3285 32 Simulated time since RESET.
