A certain three-port network is lossless and reciprocal, and has S13 = S23 and S11 = S22. Show that if port 2 is terminated with a matched load, then port 1 can be matched by placing an appropriate
A 74x163 counter is hooked up with inputs ENP, ENT, and D always HIGH, inputs A, B, and C always LOW, input LD_L = (QA.QC)', and input CLR_L = (QB.QD)'. The CLK input is hooked up to a free-running
An edge-coupled microstrip line with a ground plane spacing of 0.5 mm and dielectric constant of 10 is required to have even- and odd-mode characteristic impedances of Zoe=70 and Zoo=40
The serial ports on two computers which use binary signaling are connected by a twisted pair cable. The cable has a flat frequency response up to 120KHz, with negligible group delay distortion. That
We use the time constant to characterize transients in electric circuits. In physics, the half-life is often used to characterize the exponential decay of physical quantities such as radioactive sub
Design a simple BJT amplifier circuit for receiving the over-the-air HDTV signals. The circuit should have a voltage gain of 10-100, assuming your signal source (antenna) is connected to amp through
A clever student notices that a high constant loop gain would make the PLL converge in frequency and phase. Rather than use an amplifier with infinite gain the student decides to just use an unstabl
