Question

If both ends of a drain wire on a shield are grounded it can cause a ground loop. What is a ground loop? What causes FM reception problem called ? What causes FM reception problem called multipath? Front way noise enters from where? Sideway noise enters from where? On a normal system, with the radio turned ON. what DCV would be measured from one speaker wire to ground? ____ V what DCV would be measured across the two speaker wires? ____ V Capacitors block AC/DC current but pass AC/DC current. Trace all the circuits for the RF (right front) channel on the Grand Cherokee full system diagram (on back). Which type coax cable has less signal loss? a. RG 58/59 b. RG 62 Why? ____

Explanation / Answer

1)Ground loops induced on the screen/shield typically occur because of a difference in potential between the ground connection at the telecommunications grounding busbar

2)When FM reception is deflected by large objects like hill and buliding causes we recieve original signal from the transmitter and deflected signal.this cause sound distortion called flutter

3)Multipath distortion iscaused by the FM radio signals reflecting off objects or hillsides and reaching your radio by different paths.

4)Antenna
