Operational Amplifier

An operational amplifier also called op amp is an integrated circuit or analog circuit that takes input as a differential voltage and produces output as a single-ended voltage. It is an IC that can amplify weak electric signals.An op amp has one output p…

Textbook Question

Chapter 12, Problem 12.8EP

Design a feedback voltage amplifier to provide a voltage gain of 15. The nominal voltage source resistance is R S = 2 k Ω , and the nominal load is R L = 100 Ω . An op-amp with parameters R i = 5 k Ω , R o = 50 Ω , and a lowfrequency open-loop gain of A v = 5 × 10 3 is available. Correlate the design with a computer simulation analysis to determine the voltage gain, input resistance, and output resistance.

Open plc - ladder logic To control traffic, we have red lights to stop cars and green lights to initiate entry/exit. If a car is in the lane, then the red lights turn ON. If no cars are in the lane, then the green lights turn ON. Upon turning ON the main switch button, the main switch indicator should turn ON and the system should start with green lights ON and red lights OFF?

3-4) 3.4-2 Signals g₁(t) = 104П(104) and g2(t) = 8(t) are applied at the inputs of the ideal low-pass filters H₁(f)=(f/20,000) and H2(f) = П(f/10,000) (Fig. P3.4-2). The outputs y₁ (t) and y2(t) of these filters are multiplied to obtain the signal y(t) = y1 (1)y2(t). (a) Sketch G1(f) and G2(f). (b) Sketch H₁(f) and H₂(f). (c) Sketch Y₁ (f) and Y2(f).
