This simulation demonstrates the effects of sampling rate on analog signals. The top waveform (purple) represents the original continuous triangular signal, while the other waveforms show sampled versions at different frequencies — 1 kHz (green), 500 Hz (orange), and 250 Hz (red). As the sampling rate decreases, the reconstructed waveform becomes more distorted and loses accuracy, illustrating aliasing and quantization effects. A higher sampling rate captures more signal details, producing a wav

This simulation demonstrates how varying the sampling rate impacts the fidelity of signal reconstruction in digital systems. At the top, a sine wave is sampled and reconstructed using different ADC (Analog-to-Digital Converter) and DAC (Digital-to-Analog Converter) clock rates. As the sampling rate decreases, the reconstructed signal becomes less accurate, showing clear distortion. This highlights the importance of choosing an appropriate sampling rate—typically governed by the Nyquist theorem—t

High-frequency small-signal analysis of a common source amplifier — clearly explained This video walks through the high-frequency small-signal analysis of a common-source MOSFET amplifier, starting from the full small-signal model with parasitic capacitances included. Each parasitic element is identified and its impact on high-frequency behavior is interpreted. Using KCL and nodal analysis, the circuit is analyzed step by step to derive the frequency-dependent voltage gain. The algebra is then s
