Is there a way I can combine multiple spectrogram subplots (or multiple channel spectrograms) into just one spectrogram?
I have multiple chirp signals each with different frequencies e.g. the first chirp goes from 0 to 100 Hz, second from 50 to 200 ...

I can't seem to connect my voltage source (and hopefully for the same reason the rest) to the rest of my circuit but this to me looks the same as MATLAB's Colpitt's Oscillator? TechnicalQuestion
So my circuit is on the left, and MATLAB's Colpitt's Oscillator is on the right. I'm currently using a DC Voltage Source and...
