When the output turn to the ground‚ the electrolytic capacitor (22 µf) discharges through the second diode (D2) and it will charge the second electrolytic capacitor (10 µF) until it became a negative voltage The negative voltage can be rise up to -7V the 5.1 volt zener diode is serves as a regulator which limit the

and buried cables. Laser communications systems can be easily deployed since they are inexpensive‚ small‚ low power and do not require any radio interference studies. The carrier used for the transmission signal is typically generated by a laser diode. Two parallel beams are needed‚ one for transmission and one for reception. INTRUDUCTION: Laser Communication is one of the emerging area of wireless communication system. Due to its low noise ratio makes its one of the well suited communication

Desmosomes prevent adjacent cells from separating during contraction and gap junctions allow ions to pass from cell to cell transmitting current across the entire heart 3. What are the different effects of the PNS and SNS on heart rate? Parasympathetic slows heart rate SNS increases heart rate 4. Atrial hypertrophy would probably have what effect on
