The Stethoscope is an auditory medical appliance for listening to internal resonance in human body which is referred to, in medical language, as auscultation. Heart sound vibration is one of the most essential ways to judge the condition of the cardiac function.
The apparatus used were as follows; patch-board, farnell low frequency (LF) oscillator, oscilloscope (CD 1400 including 1 off CX1 449), digital voltmeter and digital frequency meter. Procedure The LF oscillator was connected in series of a capacitor and a resistor and the voltage across and current through the capacitor measured at frequencies between 1 kHz and 10 kHz.
Newton's First Laws is intuitive and can be seen directly at work in our daily life. For the first case, an example would be a soccer ball which will not be going anywhere unless someone kicks it or carries it. On the second case, consider a ball rolling with a constant velocity.
The LF oscillator was connected in series of a capacitor and a resistor and the voltage across and current through the capacitor measured at frequencies between 1 kHz and 10 kHz. Current was determined by
By the end of this lab, you should be able to analyse circuit behaviour when DC or AC voltages are applied to the circuits. You are required to record all activities (observations, results and comments) in your logbook as you
The experiment was aimed at confirming this by building and testing various op-amp circuits that make use of negative feedback.
The circuits are mainly built of the operational amplifier integrated circuit, and forward and feedback
