The bandwidth of the message signal m(t) is W and the transfer function of the bandpass filter is shown in the Fig.1(b). 0000002721 00000 n Problem 1. %�쏢 Solution For ASK, N = 1, and the baud and minimum bandwidth are determined from Equations 2.11 and 2.10, respectively: B = 10,000 / 1 = 10,000 baud = 10, 000 /1 = 10,000 The use of amplitude-modulated analog carriers to transport digital information is a relatively low-quality, low-cost type of digital modulation and, therefore, is seldom used except for very low-speed telemetry circuits. Get the Fourier series and … Solution By: Mark Porubsky . This technique was devised in the 20th century at a time when Landell de Moura and Reginald Fessenden were conducting experiments using a radiotelephone in the 1900s. Amplitude modulation (AM) communication systems arose from the need to send an acoustic signal, a “message”, over the airwaves using a reasonably sized antenna to radiate it. a) Determine hl(t), the lowpass equivalent of h(t), where h(t) represents the impulse response of the BPF. 0000001708 00000 n trailer << /Size 60 /Info 22 0 R /Root 25 0 R /Prev 82506 /ID[<69639f30311b78fe05567e808c9b70ae><64066740905ed263da94e27cbbf5691c>] >> startxref 0 %%EOF 25 0 obj << /Type /Catalog /Pages 21 0 R /Metadata 23 0 R /PageLabels 20 0 R >> endobj 58 0 obj << /S 154 /L 251 /Filter /FlateDecode /Length 59 0 R >> stream 0000053120 00000 n *B7_��̜`�cT��b��;^i弉��Zi>B�^��Z�ޖ��>�}��U^�m�~qd Up�ô� D�]�0��/͖_=��O=i��b}�[!��ѹX��B��WE �{�NԑBw��FYל��E�4� Figure (4.2) shows the amplitude spectra of angle-modulated signals for several values of β. 0000001067 00000 n 0000005437 00000 n A sinusoidal modulating waveform of amplitude 5 V and a frequency of 2 KHz is applied to FM generator, which has a frequency sensitivity of 40 Hz/volt. 0000002700 00000 n 0000003961 00000 n 0000001867 00000 n Read Book Amplitude Modulation Solved Problems Problem 7 Frequency Modulation (20 points) A frequency modulator is supplied with a carrier at frequency f c = 5 MHz and an audio tone signal of A m = 1 volt amplitude and Page 19/73.
