The moving coil in a dynamometer wattmeter is connected Consider the following statements S 1 and S 2 . S 1 : The threshold voltage (V T ) of a MOS capacitor decreases with increase in gate oxide thickness. S 2 : The threshold voltage (V T ) of a MOS capacitor decreases with increase in substrate doping concentration. Which one of the following is correct? An analog signal is band-limited to 4 kHz, sampled at the Nyquist rate and the samples are quantized into 4 levels. The quantized levels are assumed to be independent and equally probable. If we transmit two quantized samples per second, the information rate is Which of the following circuit exhibits memory? PAM signals are constructed by using a low pass filter of pass band slightly greater than base band to avoid aliasing. This avoids distortion
