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 =

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

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

EXECUTIVE SUMMARY The initial manufacturing of electric fans originated from India approximately in the year 1921. This growing industry entails the assembling and completion of various fans‚ such as ceiling fan‚ table fans‚ wall fans‚ pedestal fans‚ exhaust fans among many other types‚ with ceiling fans dominating the market demand. The challenge within the industry is unfortunately decreasing. As the peak season of production arises there is a shortage in the component supply (Sridharan‚ 2009)
