Pulse Generator Characteristics

• Pulse rise time • Pulse fall time

• Settling time • Pulse droop or swag

M. S. Ramaiah School of Advanced Studies 11

Pulse Generator Characteristics

• Pulse width • Pulse repetition rate

• Duty cycle • Pulse jitter

M. S. Ramaiah School of Advanced Studies 12

Pulse Generator Characteristics

• Pulse preshoot • Linearity

• Pulse ringing

M. S. Ramaiah School of Advanced Studies 13

Applications

• Pulse generators are used to drive devices such as switches, lasers and optical

components, modulators, intensifiers as well as resistive loads

• The output of a pulse generator may also be used as the modulation signal for a

signal generator

• Non-electronic applications such as material science, medical, physics, chemistry

• It is used for digital communication

• Digital MP3 players

• All digital IC pins

M. S. Ramaiah School of Advanced Studies 14

Advantages

• Simple control system

• High currents

•Good control and flexibility of time parameters

Disadvantages

• Amplitude drop during the pulse

• Low amplitude flexibility

M. S. Ramaiah School of Advanced Studies 15

Conclusion

• Pulse generator operation was explained in detail

• Pulse characteristics was also dealt with relevant explanation with pictures

• Pulse generator application was explained

• Advantages and disadvantages of different concepts of pulse generator is

summarized
