Sampling Theorem: “A bandlimited signal can be reconstructed exactly if it is sampled at a rate atleast twice the maximum frequency component in it.” Figure 1 . PDF | A derivation of the sampling theorem. | ResearchGate, the professional network for scientists. The lowpass sampling theorem states that we must sample at a rate,, at least twice that of the highest frequency of interest in analog signal. Specifically, for.

1) Sampling: Conversion of analogue signal into a discrete signal by taking sample at every Ts s. 2) Quantization: Conversion of discrete signal into discrete. An Introduction to the Sampling Theorem. With rapid advancement in data acquistion technology (i e analog-to-digital and digital-to-analog converters) and the. It was not until these papers were published that the theo- rem known as “ Shannon's sampling theorem” became com- mon property among communication.

Circuit diagram Fig 1: Reconstructing circuit Procedures 1. The circuit is connected as per the circuit diagram shown in fig 1.

Apply the sinusoidal signal of approximately 4v p-p at Hz frequency and pulses signal of 11V p-p with frequency between Hz and 4KHz.

Connect the sampling circuit output and AF signal to the inputs of oscilloscope.

Initially set the potentiometer to the minimum level and sampling frequency to Hz and observe the output on the CRO. Now by adjusting the potentiometer, vary the amplitude of modulating signal and observe the output of sampling circuit.
