(a) Now consider a typical open-wire transmission line with parameters of R = 14 /mi, L = 4.6 mH/mi, C = 0.01 µF/mi, and G = 0.3×10-6S/mi. If the line operates at 1 kHz, find the characteristic impedance ¯ Z0 and the propagation constant ¯ γ .
(b) Then consider a 100-mi open-wire ?at telephone line with the same parameters as those given in part (a). The matched transmissionline is shown in Figure P15.1.18(b). If the frequency of the generator is 1 kHz, determine the following:
(i) Sending-end current ¯ IS .
(ii) Sending-end voltage ¯ ES .
(iii) Sending-end power PS.
(iv) Receiving-end current ¯ IR.
(v) Receiving-end voltage ¯ ER.
(vi) Receiving-end power PR.
(vii) Power loss in dB, which is given by 10 log (PS/PR).
Electronic voltage regulators: Electronic voltage regulators operate through comparing the actual output voltage to a few internal fixed reference voltages. Any type of differ
Q. Write a note on clampers ? Clamper is a circuit that "clamps" a signal to a different dc level. The different types of clampers are positive negative and biased clampers.

Q. If the line of Problem 15.1.3 is made of copper whose resistivity ρ = 1.72×10 -8 ·m, determine the maximum length that can be used if losses are not to exceed 3 dB when f = 3
Decrement contents of Register The contents of register R will be decremented by one and the result is stored in the same register R. It is also an exceptional case i
Astigmation control: In most modern oscilloscopes there is an additional focusing control marked Astigmation . This is used to correct an effect which exactly is analogous to
Suppose that a video signal, having W = 5 MHz, is transmitted via FM with f = 20 MHz. For 1/100 ≤ B/fc ≤ 1/10, determine the bounds on the carrier frequency. Use WFM ∼ = 2( ω + 2W
Alternate Representation for Complex Poles Complex poles can be combined to yield a quadratic term in the partial fraction expansion. The representation may best be illustrated
