Gear Wheel Method for Frequency Measurement: When a Lissajous figure contains a large number of loops, accurate counting becomes difficult. Figure 7.35 shows a test method that uses a modulated…

Spot Wheel Method for Frequency Measurement: As the ratio of the two frequencies being compared increases, the Lissajous pattern becomes more complicated and hence more difficult to interpret. In such…

Dual Trace Oscilloscope: Figure 7.19 (a) shows a block diagram of Dual Trace Oscilloscope. This CRO has a single electron gun whose electron beam is split into two by an…

Trigger Pulse Generator Circuit: The Trigger Pulse Generator Circuit is activated by signals of a variety of shapes and amplitudes, which are converted to trigger pulses of uniform amplitude for…

Horizontal Deflection System in CRO: The Horizontal Deflection System in CRO consist of a Time Base Generator and an output amplifier. Sweep or Time Base Generator: A continuous sweep CRO…
