a square wave of 1000Hz is introduced into an ideal band passfilter (bandwidth = 100Hz) that is tuned to 5000Hz. Thesignal output has an amplitude of 0.1V. The filster is thenreturned to 9000Hz. Sketch the output waveform and calculate itsnew amplitude.
A TTl gate with VIH (min) = 2.25 V and VIL (max) = 0.65 V is being driven by a gate with NOH (min) = 2.4 V and VOL (max) = 0.4 V. What is the maximum amplitude of noise spikes that can be tolerated on the inputs in both the HIGH and LOW states
A car battery has an open-terminal voltage of 12 V and an internal resistance of 0.02 . If the car starter has a resistance of 0.10 in series with the batter, what is the resulting terminal voltage on the starter
a) Using 10 nF capacitors and ideal op amps, PROBLEM design a high-pass unity-gain Butterworth filter with a cutoff frequency of 2 kHz and a gain of no more than -48 dB at 500 Hz. b) Draw a circuit diagram of the filter and label all component valu..
A spread-spectrum acquisition system uses a serial search scheme.The synchroniser integrates the squarer output for interval of 0.1s and the synchroniser output is sampled at intervals of 0.05s . The probability of false alarm is 0.064255 .
A portable battery supplies electricity to an external circuit for 2 hours. The voltage across the terminals of the battery is observed to increase from initial voltage of 5V to 10V (linearly) and the current increases from 1A to 2A (linearly) in ..
what is the new resistance level of a copper conductor wire if the lenght is changed from 200 ft to 400 ft, the area is changed from 50,000 CM to 0.10 in ^2 and the original resistance was 7 ohms
If 3.0 V are across the resistor, compute: a) the current in the inductor b) the inductive reactance XL c) the voltage across the inductor Vl d) the source voltage Vs e) the phase angle between Vr and Vs
mesh analysis involves writing and solving a number of simultaneous equations. The number of equations is equal to the number of independent loops in the circuit. Each equation is derived from the application of KVL around the loop.
