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

Green revolution Green Revolution refers to a series of research‚ development‚ and technology transfer initiatives‚ occurring between the 1940s and the late 1970s‚ that increased agriculture production around the world‚ beginning most markedly in the late 1960s. It forms a part of the ’neo-colonial’ system of agriculture wherein agriculture was viewed more of a commercial sector than a subsistence one.[1] The initiatives‚ led by Norman Borlaug‚ the "Father of the Green Revolution" credited with

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)

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
