As U found 2g and 3g in telecom, You also have cable network, fiber network, wireless network, wi-fi, wi-max, wi-bro..... so everyneed will give birth to a new invention and as telecom is growing, even network will equally grow....
Is it possible to have a mixed signal testing on board or PCB? If there is no bed-of-nail available and if one has to make a test jig or the test setup, can we still test or run JTAG, scan chain test, BIST on it?
