Fm waveform's
WebThe received FM waveform is a 100 kHz carrier modulated by a 100 Hz sinusoid. We’re using the same quadrature demodulator that was used in the AM simulation; it has two arbitrary behavioral voltage sources for performing the multiplication, and each voltage source is followed by a two-pole low-pass filter (the cutoff frequency is ~1 kHz). WebAn LFM pulse is one in which the "instantaneous frequency" changes linearly over the duration of the pulse. By "instantaneous frequency" I mean the rate of change of phase. Over its τ = 500 μ s duration, a pulse with "bandwidth" B = 50 k H z and center frequency f c = 150 k H z would be defined by. We can see that this sweeps from 2 π ( f c ...

Amplitude Modulation (AM) is the simplest analog modulation method to implement. Here a signal is used to slowly vary the amplitude of the carrier according to the level of the modulating signal. With AM (Figure 2.4.1 (c)) the amplitude of the carrier is modulated, and this results in a broadening of the spectrum of ...
