This is a BJT amplifier circuit simulation with its input and output waveforms. The green trace represents the input AC signal (1 kHz sine wave), while the red trace shows the amplified output signal. The circuit uses a common-emitter configuration with biasing resistors and coupling capacitors. The output clearly has a higher amplitude (approx. 1.74 V peak-to-peak) compared to the input (approx. 500 mV), demonstrating the voltage gain typical of a BJT amplifier stage. #ElectronicsEducation #ele
