电路包络仿真Lab_99 This chapter shows how to use Circuit Envelope to measure time and frequency of an output signal when the input is a modulated source such as GSM, CDMA, etc. Lab 9: Circuit Envelope Simulations Lab 9: Circuit Envelope Simulation OBJECTIVES Learn basic Circuit Envelope set up and simulation Simulate the response of a behavioral amp with a filter Simulate the Mixer with the Envelope Simulator About this 2 part lab: Part A uses a behavioral amplifier to demonstrate basic Circuit Envelope simulation using a modulated signal and then measures the output envelope response in both time and frequency. Part B uses the mixer circuit where you can apply the techniques and perform more complex measurements. PROCEDURE Part A: CE basics with a behavioral amp 1. Create a new schematic design:……
