To generate just one function, eliminate the resistor for the other function and ground the current source. If necessary, a high impedance buffer circuit can be added. Note that the output impedance of the circuit varies with time (from 0 to 1mΩ in this example) but that should not cause a significant error in most circuits. The peak output voltage is equal to I1/1000, thus giving a peak value of 1V for the shown value of 1000A. ![]() Thus sin(2pi*time*1k) gives a sine modulation frequency of one cycle per ms or 1kHz. The modulation frequency is (2pi*time*X), where time is the simulation time and X is an arbitrary constant. This provides a carrier phase reversal for alternate half-cycles of the modulation signal, which is characteristic of a DSB modulated signal. The function works to generate a simulated negative resistance for the DSB generation. #Ltspice ac source generator#LTspice does not have a generator for amplitude modulation so here's a way to do that.īelow is a simulation of using a sine function to vary a resistance with time, along with an AC current-source, to generate an AM signal and a DSB suppressed-carrier modulated signal. ![]()
