Here is the characteristics of a single pulse.
- The voltage rises very rapidly from zero to its maximum value.
- It stays steady at the maximum value for a time.
- It then falls very rapidly back to zero.
- The duration of a pulse can be anywhere from a very long time (days) to a very short time (picoseconds or less).
- Pulses do not rise and fall instantaneously but take time (which may be very short).
- They are called the RISE and FALL times.
If pulses occur one after another they are called a PULSE TRAIN. Fig. 3 has a 50:50 mark/space ratio. Note that the last three waveforms are of the same frequency. All the pulses start at the same instant. |
