Laboratory 3: Diode Characteristics Instructions: Unless otherwise mentioned in the experiment instructions‚ all experiments are performed both in SPICE and physical implementation. The results need to be reported from both the SPICE and physical measurements. 1 Current voltage characteristics of diodes 1. Design a circuit to measure the forward-bias current voltage characteristics of diode as shown in Fig 3 using Circuitlab. Figure 1: A SPICE circuit for plotting current voltage

Tutorial Sheet # 2 1. Sketch the time variation and frequency spectrum of an RF signal with 75 % Amplitude Modulation. Show several cycles of the modulated wave. Make the modulation frequency 1/10 of the carrier frequency. The unmodulated carrier has peak amplitude of 1.0V. In an amplitude modulation system‚ the message signal is given by Fig. and the carrier frequency is 1 KHz. The modulator output is SAM (t) = 2(b + 0.5m (t)) cos ωc t. 2. a. Determine the average message power. b. If b =

Task 3: In order to modify the circuit that we created in TASK2 by adding the capacitors C1‚ C2 and C3 and fixing the value of R2 to be 10K‚ as shown in figure. We were asked to calculate the voltage gain of the amplifier for the two different values of Rc. Figure 2 Source: Figure 2 Source: In this task we used the function generator to produce a sine wave of 30mV and 50mV Vp-p at the frequency of 50 KHz. We connected CH1 to fed this generated signal in the oscilloscope at Vin. In

------------------------------------------------- OBJECT ORIENTED PROGRAMMING Q.What is the difference between Constructor and Function or Method? Constructor will be automatically invoked when an object is created whereas method has to be called explicitly. Constructor needs to have the same name as that of the class whereas functions need not be the same. * There is no return type given in a constructor signature (header). The value is this object itself so there is no need to indicate a

The Effectiveness of Acceptances Communicated by Electronic Means‚ or — Does the Postal Acceptance Rule Apply to Email? Eliza Mik* The ‘traditional’ classification into ‘instantaneous’ and ‘non-instantaneous’ methods of communication must be abandoned. As all Internet transmissions are instantaneous‚ the choice between the principle of receipt and the postal exception must be based on other criteria. The focus must be shifted from communication devices to the characteristics of the communication

An electronic funds transfer (also known as EFT) is a system for transferring money from one bank to another without using paper money. Its use has become widespread with the arrival of personal computers‚ cheap networks‚ improved cryptography and the Internet. Since it is affected by financial fraud‚ the electronic funds transfer act was implemented. This federal law protects the consumer in case a problem arises at the moment of the transaction. The history electronic funds transfer originated
