In push-pull amplifiers there will be no current through the
transistor unless the input voltage goes greater than
in the forward direction and
in the reverse direction. This will cause a cross over distortion
to happen. Now if we insert two diodes between the bases this
problem can be avoided. Hence the voltage between the bases(Trickle
bias) will be close to
. If we take the cut in voltage as 0.7V, the net potential
difference(Trickle bias) between the bases will be 1.4V.
Trickle bias on a CC push-pull amplifier should place approximatley ........ V between the bases

D7.35 The bias arrangement of Fig. 7.53 is to be used for a common-base amplifier. Design the circuit to establish a de emitter current of I mA and provide the highest possible voltage gain while allowing for a signal swing at the collector of ±2 V. Use + 10-V and-5-V power supplies. Cc Rc UC RB RE
1. (15%) Describe the difference between a pull (Kanban), push and CONWIP production systems.
You should feel a slight resistance when you try to push and pull the electromagnet into the coil. Where does this come from and what is the direction of this force? Why did it become harder to move the magnet into the coiled loop of wire as more wires were added, as you moved the magnet faster, or as the area of the loop was bigger?
What is inflation? What is the difference between demand-pull and cost-push inflation? Have you seen any evidence of increased inflation where you live? How is inflation calculated?
