What device is used to demodulate a time division multiplexed analog wave?(a) High pass filter(b) Low pass filter(c) Band stop filter(d) Attenuator |
|
Answer» Correct answer is (b) Low pass filter Explanation: the analog signal is converted to a series of constant-width pulses whose amplitude follows the shape of the analog signal. The original analog signal is recovered by passing it through a low-pass filter. In TDM using PAM, a circuit called a multiplexer (MUX or MPX) samples multiple analog signal sources; the resulting pulses are interleaved and then transmitted over a single channel. |
