In a cathode ray oscilloscope, CRO, the electron beam is directed towards a fluorescent screen. The cathode ray oscilloscope (CRO) provides a visual presentation of any waveform applied to the input terminal. %PDF-1.6 %���� The Cathode Ray Oscilloscope Introduction The following should give the student some familiarisation with the function and uses of the cathode ray oscilloscope (C.R.O.). {’�zqa�'���O��k�&��_�o߳` AȄ���&�g K��'F��y?���{_>���7�����������2����! 15 0 obj << �Ɗ��Z��%�[1k}馆z��T.Ev߈�D�4�f'O�D��\�S��� s�Db=\P��v�7��{� /Type /Page <> '��Ʈ�Z The CRO stands for a cathode ray oscilloscope. endobj 10 0 obj <> (PDF) oscilloscope.pdf | Amna Khalid - A cathode ray oscilloscope (CRO) is used to represent a waveform on an instrument and CRO provides best source as a digital instrument for representing and studying the waveforms.
