If the R25 Value of the thermistor 'TH1', in the circuit above, is 47 K, what value would you suggest for R1 if you are monitoring temperatures in the range of 25°C?

1. Consider the following sequential circuit given in Figure 1 (a) Determine the circuit's characteristic equations. (b) Determine the circuit's state-transition table. (c) Determine the circuit's state-transition diagram.

Given that the gain, A, of an inverting amplifier is given by: A=-\frac{R_{F}}{R_{I N}} What are the switch positions for 'SW1' and 'SW2' to achieve a gain of approximately -2.222 'SW1' in position '1' and 'SW2' in position '4' O'SW1' in position '4' and 'SW2' in position '2'

The 'INH' pin of the CD4052B, shown above, has been set to 5V in the circuit shown above.What is the value of VOUT?

\text { Consider the passband signal } u_{p}(t)=\operatorname{sinc}(20 t)^{2} \cos (2000 \pi t)+\operatorname{sinc}(20 t) \sin (2000 \pi t) \text {. } (a) Find uc and us, the I and Q components of the signal, using the reference frequency fe = 1000. (b) Find Uc and Us, the spectra of the I and Q components. (c) Find u(t), the complex envelope, and e(t), the envelope. (d) Find the bandwidth of u, and the bandwidth of u. (For the definition of bandwidth of a passband signal, use the convention of equation (2.67) and the lecture notes, not of Figure 2.25.) (e) Draw a circuit using multipliers and low pass filters that extracts uc and us from the passband signal up- (f) Assume that each of the filters in the previous part have ideal low pass frequency responses.Specify the interval of possible choices for the upper end of the frequency band passed by each filter.

Object: To investigate the terminal characteristics of operational amplifiers and to see how they are used as dependent sources. Check experimental values using videos. Then find calculated values using it also the calculated values including the percentage difference column and then make a table in word file of both values!
