In the case of the 2N transistor, which had a higher Beta than the 2N transistor, the Q point of the former shifted higher up the loadline toward saturation.

In case of sinusoidal voltages, the advantage is probably with the DMM. The magnitude of the Beta of a transistor is a property of the device, etoria of the circuit. This would increase descarbar quiescent current, lower the dynamic resistance re and consequently increase the gain of the amplifier. This is expected since the resistor R2, while decreasing the current gain of the circuit, stabilized the circuit in regard to any current changes.

For reverse-bias potentials in excess of 10 V the capacitance levels off at about 1. Thus, there should not be much of a change in the voltage and current levels if the transistors are interchanged.


They should be relatively close to each other. Half-Wave Rectification continued b.

See probe plot page The Beta of the transistor is increasing. There are five clock pulses to the left of the cursor. A better expression for the output impedance is: Beta did increase with increasing levels of VCE. Copper has 20 orbiting electrons with only one electron in the outermost shell.

This circuit would need to be redesigned to make it a practical circuit. The pulse of milliseconds of the TTL pulse is identical to that of the simulation pulse.

cigcuitos Note that the slope of the curves in the forward-biased region is about the same at different levels of diode current. For the positive region of vi: With potentiometer set at top: The logic states of the simulation and those experimentally determined are identical.

Again, depending on how good the design of the voltage divider bias circuit is, the changes in the circuit voltages and currents should be kept to a minimum. The variations for Alpha and Beta for the tested transistor are not really significant, resulting in an almost ideal current source which is independent of the voltage VCE. In equation 4a, the Beta factor cannot be eliminated by a judicious choice of circuit components. Consequently, small levels of reverse voltage can result in a significant current levels.


The voltage at the output terminal was 3. Both waveforms are in essential agreement. The output of the gate is the negation of the output of the gate.

It depends upon the waveform. Same basic appearance as Fig. The Q point shifts toward saturation along the loadline. Skip to main content. See Probe plot The Betas desfargar about the same. Shunt Voltage Regulator a. The vertical shift of the waveform was equal to the battery voltage. See data in Table 9.

Theoretically, the most ,ibro of the two collector feedback circuits should be the one with a finite RE. Q terminal is 5 Hz. For more complex waveforms, the nod goes to the oscilloscope. Clampers R, C, Diode Combination b.

The higher the peak value of descatgar gate current the sooner the triggering level will be reached and conduction initiated. Darlington Input and Output Impedance a.
