R, low out Output current Figure Magnetic time base The linearly rising current in L^ {Figure ) suggests that a circuit along the lines of the converter might be used as a time-base generator for a magnetically deflected cathode ray tube. In fact this is quite possible; the time-base circuit has the appearance of Figure , and has been used by the author for an experimental transistorized oscilloscope. The energy in the magnetic field following each growth has to be recovered from across Deflector coils t—nsM^ Sync ^ current Sweep amplitude.
